## Prerequisites

`gio.File` is implemented by `gobject.GObject`

## Description

`gio.File` is a high level abstraction for manipulating files on a virtual file system. `gio.File`s are lightweight, immutable objects that do no I/O upon creation. It is necessary to understand that `gio.File` objects do not represent files, merely an identifier for a file. All file content I/O is implemented as streaming operations (see `gio.InputStream` and `gio.OutputStream`).

To construct a `gio.File`, you can use it's constructor either with a path, an uri or a commandline argument. `gio.file_parse_name`() from a utf8 string gotten from `gio.File.get_parse_name`().

One way to think of a `gio.File` is as an abstraction of a pathname. For normal files the system pathname is what is stored internally, but as `gio.File`s are extensible it could also be something else that corresponds to a pathname in a userspace implementation of a filesystem.

`gio.File`s make up hierarchies of directories and files that correspond to the files on a filesystem. You can move through the file system with GFile using `gio.File.get_parent`() to get an identifier for the parent directory, `gio.File.get_child`() to get a child within a directory, `gio.File.resolve_relative_path`() to resolve a relative path between two `gio.File`s. There can be multiple hierarchies, so you may not end up at the same root if you repeatedly call `gio.File.get_parent`() on two different files.

All `gio.File`s have a basename (get with `gio.File.get_basename`() ). These names are byte strings that are used to identify the file on the filesystem (relative to its parent directory) and there is no guarantees that they have any particular charset encoding or even make any sense at all. If you want to use filenames in a user interface you should use the display name that you can get by requesting the gio.FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME attribute with `gio.File.query_info`(). This is guaranteed to be in utf8 and can be used in a user interface. But always store the real basename or the GFile to use to actually access the file, because there is no way to go from a display name to the actual name.

Using `gio.File` as an identifier has the same weaknesses as using a path in that there may be multiple aliases for the same file. For instance, hard or soft links may cause two different `gio.File`s to refer to the same file. Other possible causes for aliases are: case insensitive filesystems, short and long names on Fat/NTFS, or bind mounts in Linux. If you want to check if two GFiles point to the same file you can query for the gio.FILE_ATTRIBUTE_ID_FILE attribute. Note that `gio.File` does some trivial canonicalization of pathnames passed in, so that trivial differences in the path string used at creation (duplicated slashes, slash at end of path, "." or ".." path segments, etc) does not create different `gio.File`s.

Many `gio.File` operations have both synchronous and asynchronous versions to suit your application. Asynchronous versions of synchronous functions simply have _async() appended to their function names. The asynchronous I/O functions call a GAsyncReadyCallback which is then used to finalize the operation, producing a GAsyncResult which is then passed to the function's matching _finish() operation.

Some `gio.File` operations do not have synchronous analogs, as they may take a very long time to finish, and blocking may leave an application unusable. Notable cases include: `gio.File.mount_mountable`() to mount a mountable file. `gio.File.unmount_mountable`() to unmount a mountable file. `gio.File.eject_mountable`() to eject a mountable file.

One notable feature of `gio.File`s are entity tags, or "etags" for short. Entity tags are somewhat like a more abstract version of the traditional mtime, and can be used to quickly determine if the file has been modified from the version on the file system. See the HTTP 1.1 specification for HTTP Etag headers, which are a very similar concept.

## Constructor

        gio.File(commandline, path=None, uri=None)

`commandline` : | a command line string.
`path` : | a string containing a relative or absolute path.
`uri` : | a string containing a URI.
Returns : | a new `gio.File`.

Creates a new `gio.File` either from a commandline, a path or an uri.

## Methods

### gio.File.append_to

        def append_to(flags=gio.FILE_CREATE_NONE, cancellable=None)

`flags` : | a set of Gio File Create Flags Constants
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a `gio.FileOutputStream` or `None` on error.

The `append_to`() method gets an output stream for appending data to the file. If the file doesn't already exist it is created.

By default files created are generally readable by everyone, but if you pass gio.FILE_CREATE_PRIVATE in flags the file will be made readable only to the current user, to the level that is supported on the target filesystem.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

Some file systems don't allow all file names, and may return an gio.ERROR_INVALID_FILENAME error. If the file is a directory the gio.ERROR_IS_DIRECTORY error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

### gio.File.append_to_async

        def append_to_async(callback, flags=gio.FILE_CREATE_NONE, io_priority=glib.PRIORITY_DEFAULT, cancellable=None, user_data=None)

`callback` : | a GAsyncReadyCallback to call when the request is satisfied.
`flags` : | a set of Gio File Create Flags Constants.
`io_priority` : | the Glib Priority Constants of the request.
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
`user_data` : | the data to pass to callback function.

The `append_to_async`() method asynchronously opens file for appending.

For more details, see `gio.File.append_to`() which is the synchronous version of this call.

When the operation is finished, callback will be called. You can then call `gio.File.append_to_finish`() to get the result of the operation.

### gio.File.append_to_finish

        def append_to_finish(result)

`result` : | a `gio.AsyncResult`.
Returns : | a valid `gio.OutputStream` or `None` on error.

The `append_to_finish`() method finishes an asynchronous file append operation started with `gio.File.append_to_async`().

### gio.File.copy

        def copy(destination, progress_callback, flags=gio.FILE_COPY_NONE, cancellable=None, user_data=None)

`destination` : | destination `gio.File`.
`progress_callback` : | function to callback with progress information.
`flags` : | a set of Gio File Copy Flags Constants
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
`user_data` : | the data to pass to the progress callback function.
Returns : | `True` on success, `False` otherwise.

The `copy`() method copies the file source to the location specified by destination. Can not handle recursive copies of directories.

If the flag gio.FILE_COPY_OVERWRITE is specified an already existing destination file is overwritten.

If the flag gio.FILE_COPY_NOFOLLOW_SYMLINKS is specified then symlinks will be copied as symlinks, otherwise the target of the source symlink will be copied.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

If progress_callback is not `None`, then the operation can be monitored by setting this to a GFileProgressCallback function. user_data will be passed to this function. It is guaranteed that this callback will be called after all data has been transferred with the total number of bytes copied during the operation.

If the source file does not exist then the gio.ERROR_NOT_FOUND error is returned, independent on the status of the destination.

If gio.FILE_COPY_OVERWRITE is not specified and the target exists, then the error gio.ERROR_EXISTS is returned.

If trying to overwrite a file over a directory the gio.ERROR_IS_DIRECTORY error is returned. If trying to overwrite a directory with a directory the gio.ERROR_WOULD_MERGE error is returned.

If the source is a directory and the target does not exist, or gio.FILE_COPY_OVERWRITE is specified and the target is a file, then the gio.ERROR_WOULD_RECURSE error is returned.

If you are interested in copying the `gio.File` object itself (not the on-disk file), see `gio.File.dup`().

### gio.File.copy_async

        def append_to_async(destination, callback, progress_callback=None, flags=gio.FILE_CREATE_NONE, io_priority=glib.PRIORITY_DEFAULT, cancellable=None, user_data=None, progress_callback_data=None)

`destination` : | destination `gio.File`.
`callback` : | a GAsyncReadyCallback to call when the request is satisfied.
`progress_callback` : | function to callback with progress information.
`flags` : | a set of Gio File Copy Flags Constants.
`io_priority` : | the Glib Priority Constants of the request.
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
`user_data` : | the data to pass to callback function.
`progress_callback_data` : | the data to pass to the progress callback function.

The `copy_async`() method copies the file source to the location specified by destination asynchronously. For details of the behaviour, see `gio.File.copy`().

If progress_callback is not `None`, then that function that will be called just like in `gio.File.copy`(), however the callback will run in the main loop, not in the thread that is doing the I/O operation.

When the operation is finished, callback will be called. You can then call `gio.File.copy_finish`() to get the result of the operation.

### gio.File.copy_attributes

        def copy_attributes(destination, flags=gio.FILE_COPY_NONE, cancellable=None)

`destination` : | destination `gio.File` to copy attributes to.
`flags` : | a set of Gio File Copy Flags Constants
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | `True` if the attributes were copied successfully, `False` otherwise.

The `copy_attributes`() method copies the file attributes from source to destination.

Normally only a subset of the file attributes are copied, those that are copies in a normal file copy operation (which for instance does not include e.g. owner). However if gio.FILE_COPY_ALL_METADATA is specified in flags, then all the metadata that is possible to copy is copied. This is useful when implementing move by copy + delete source.

### gio.File.copy_finish

        def copy_finish(result)

`result` : | a `gio.AsyncResult`.
Returns : | `True` on success, `False` on error.

The `copy_finish`() method finishes an asynchronous copy operation started with `gio.File.copy_async`().

### gio.File.create

        def create(flags=gio.FILE_CREATE_NONE, cancellable=None)

`flags` : | a set of Gio File Create Flags Constants
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a `gio.FileOutputStream` or `None` on error.

The `create`() method creates a new file and returns an output stream for writing to it. The file must not already exist.

By default files created are generally readable by everyone, but if you pass gio.FILE_CREATE_PRIVATE in flags the file will be made readable only to the current user, to the level that is supported on the target filesystem.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

If a file or directory with this name already exists the gio.ERROR_EXISTS error will be returned. Some file systems don't allow all file names, and may return an gio.ERROR_INVALID_FILENAME error, and if the name is to long gio.ERROR_FILENAME_TOO_LONG will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

### gio.File.create_async

        def create_async(callback, flags=gio.FILE_CREATE_NONE, io_priority=glib.PRIORITY_DEFAULT, cancellable=None, user_data=None)

`callback` : | a GAsyncReadyCallback to call when the request is satisfied.
`flags` : | a set of Gio File Copy Flags Constants.
`io_priority` : | the Glib Priority Constants of the request.
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
`user_data` : | the data to pass to callback function.

The `create_async`() method asynchronously creates a new file and returns an output stream for writing to it. The file must not already exist.

For more details, see `gio.File.create`() which is the synchronous version of this call.

When the operation is finished, callback will be called. You can then call `gio.File.create_finish`() to get the result of the operation.

### gio.File.create_finish

        def create_finish(result)

`result` : | a `gio.AsyncResult`.
Returns : | a `gio.FileOutputStream` or `None` on error.

The `create_finish`() method finishes an asynchronous copy operation started with `gio.File.create_async`().

### gio.File.delete

        def delete(cancellable)

`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | `True` if the file was deleted, `False` otherwise.

The `deleted`() method deletes a file. If the file is a directory, it will only be deleted if it is empty.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

### gio.File.dup

        def dup()

Returns : | a new `gio.File` that is a duplicate of the given `gio.File`.

The `dup`() method duplicates a `gio.File` handle. This operation does not duplicate the actual file or directory represented by the `gio.File`; see `gio.File.copy`() if attempting to copy a file.

This call does no blocking i/o.

### gio.File.eject_mountable

        def eject_mountable(callback, flags=gio.FILE_CREATE_NONE, cancellable=None, user_data=None)

`callback` : | a GAsyncReadyCallback to call when the request is satisfied.
`flags` : | a set of Gio File Copy Flags Constants.
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
`user_data` : | the data to pass to callback function.

The `eject_mountable`() method starts an asynchronous eject on a mountable. When this operation has completed, callback will be called with user_user data, and the operation can be finalized with `gio.File.eject_mountable_finish`().

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

### gio.File.eject_mountable_finish

        def eject_mountable_finish(result)

`result` : | a `gio.AsyncResult`.
Returns : | `True` if the file was ejected successfully, `False` on error.

The `create_finish`() method finishes an asynchronous copy operation started with `gio.File.create_async`().

### gio.File.enumerate_children

        def enumerate_children(attributes, flags=gio.FILE_QUERY_INFO_NONE, cancellable=None)

`attributes` : | an attribute query string.
`flags` : | a set of Gio File Query Info Flags Constants
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a `gio.FileEnumerator` or `None` on error.

The `enumerate_children`() method gets the requested information about the files in a directory. The result is a GFileEnumerator object that will give out `gio.FileInfo` objects for all the files in the directory.

The attribute value is a string that specifies the file attributes that should be gathered. It is not an error if it's not possible to read a particular requested attribute from a file - it just won't be set. attribute should be a comma-separated list of attribute or attribute wildcards. The wildcard "*" means all attributes, and a wildcard like "standard::*" means all attributes in the standard namespace. An example attribute query be "standard::*,owner::user". The standard attributes are available as defines, like gio.FILE_ATTRIBUTE_STANDARD_NAME.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

If the file does not exist, the gio.ERROR_NOT_FOUND error will be returned. If the file is not a directory, the gio.FILE_ERROR_NOTDIR error will be returned. Other errors are possible too.

### gio.File.enumerate_children_async

        def enumerate_children_async(attributes, callback, flags=gio.FILE_QUERY_INFO_NONE, io_priority=glib.PRIORITY_DEFAULT, cancellable=None, user_data=None)

`attributes` : | an attribute query string.
`callback` : | a GAsyncReadyCallback to call when the request is satisfied.
`flags` : | a set of Gio File Query Info Flags Constants.
`io_priority` : | the Glib Priority Constants of the request.
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
`user_data` : | the data to pass to callback function.

The `enumerate_children_async`() method asynchronously gets the requested information about the files in a directory. The result is a `gio.FileEnumerator` object that will give out `gio.FileInfo` objects for all the files in the directory.

For more details, see `enumerate_children`() which is the synchronous version of this call.

### gio.File.eject_mountable_finish

        def enumerate_children_finish(result)

`result` : | a `gio.AsyncResult`.
Returns : | a `gio.FileEnumerator` or `None` if an error occurred.

The `enumerate_children_finish`() method finishes an asynchronous copy operation started with `gio.File.enumerate_children_async`().

### gio.File.equal

        def equal(file2)

`file2` : | a `gio.File`.
Returns : | `True` if file1 and file2 are equal. `False` if either is not a `gio.File`.

The `equal`() method checks equality of two given `gio.File`s. Note that two `gio.File`s that differ can still refer to the same file on the filesystem due to various forms of filename aliasing.

This call does no blocking i/o.

### gio.File.find_enclosing_mount

        def enumerate_children(cancellable=None)

`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a `gio.Mount` or `None` on error.

The `find_enclosing_mount`() method gets a `gio.Mount` for the `gio.File`.

If the interface for file does not have a mount (e.g. possibly a remote share), error will be set to gio.ERROR_NOT_FOUND and `None` will be returned.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

### gio.File.find_enclosing_mount_async

        def find_enclosing_mount_async(callback, io_priority=glib.PRIORITY_DEFAULT, cancellable=None, user_data=None)

`callback` : | a GAsyncReadyCallback to call when the request is satisfied.
`io_priority` : | the Glib Priority Constants of the request.
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
`user_data` : | the data to pass to callback function.

The `find_enclosing_mount_async`() method asynchronously gets the mount for the file.

For more details, see `gio.File.find_enclosing_mount`() which is the synchronous version of this call.

### gio.File.find_enclosing_mount_finish

        def find_enclosing_mount_finish(result)

`result` : | a `gio.AsyncResult`.
Returns : | a `gio.Mount` or `None` if an error occurred.

The `find_enclosing_mount_finish`() method finishes an asynchronous find mount started with `gio.File.find_enclosing_mount_async`().

### gio.File.get_basename

        def get_basename()

Returns : | string containing the `gio.File`'s base name, or `None` if given `gio.File` is invalid.

The `get_basename`() method gets the base name (the last component of the path) for a given `gio.File`.

If called for the top level of a system (such as the filesystem root or a uri like sftp://host/) it will return a single directory separator (and on Windows, possibly a drive letter).

The base name is a byte string (*not* UTF-8). It has no defined encoding or rules other than it may not contain zero bytes. If you want to use filenames in a user interface you should use the display name that you can get by requesting the gio.FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME attribute with `gio.File.query_info`().

This call does no blocking i/o.

### gio.File.get_child

        def get_child(name)

`name` : | string containing the child's basename.
Returns : | a `gio.File` to a child specified by name.

The `get_child`() method gets a child of file with basename equal to name.

Note that the file with that specific name might not exist, but you can still have a `gio.File` that points to it. You can use this for instance to create that file.

This call does no blocking i/o.

### gio.File.get_child_for_display_name

        def get_child_for_display_name(display_name)

`display_name` : | string to a possible child.
Returns : | a `gio.File` to the specified child or `None` if the display name couldn't be converted.

The `get_child_for_display_name`() method gets the child of file for a given display_name (i.e. a UTF8 version of the name). If this function fails, it returns NULL and error will be set. This is very useful when constructing a GFile for a new file and the user entered the filename in the user interface, for instance when you select a directory and type a filename in the file selector.

This call does no blocking i/o.

### gio.File.get_parent

        def get_parent()

Returns : | a `gio.File` structure to the parent of the given `gio.File` or `None` if there is no parent.

The `get_parent`() method gets the parent directory for the file. If the file represents the root directory of the file system, then `None` will be returned.

This call does no blocking i/o.

### gio.File.get_parse_name

        def get_parse_name()

Returns : | a string containing the `gio.File`'s parse name.

The `get_parse_name`() method gets the parse name of the file. A parse name is a UTF-8 string that describes the file such that one can get the `gio.File` back using `gio.file_parse_name`().

This is generally used to show the `gio.File` as a nice full-pathname kind of string in a user interface, like in a location entry.

For local files with names that can safely be converted to UTF8 the pathname is used, otherwise the IRI is used (a form of URI that allows UTF8 characters unescaped).

This call does no blocking i/o.

### gio.File.get_path

        def get_path()

Returns : | a string containing the `gio.File`'s path, or `None` if no such path exists.

The `get_path`() method gets the local pathname for `gio.File`, if one exists.

This call does no blocking i/o.

### gio.File.get_relative_path

        def get_relative_path(descendant)

`descendant` : | input `gio.File`.
Returns : | string with the relative path from descendant to parent, or `None` if descendant doesn't have parent as prefix.

This call does no blocking i/o.

### gio.File.get_uri

        def get_uri()

Returns : | a string containing the `gio.File`'s URI.

The `get_uri`() method gets the URI for the file.

This call does no blocking i/o.

### gio.File.get_uri_scheme

        def get_uri_scheme()

Returns : | a string containing the URI scheme for the `gio.File`.

The `get_uri_scheme`() method gets the URI scheme for a `gio.File`. RFC 3986 decodes the scheme as:

    URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ]

Common schemes include "file", "http", "ftp", etc.

This call does no blocking i/o.

### gio.File.has_prefix

        def has_prefix(prefix)

`prefix` : | input `gio.File`.
Returns : | `True` if the files's parent, grandparent, etc is prefix. `False` otherwise.

The `has_prefix`() method checks whether file has the prefix specified by prefix. In other word, if the names of inital elements of files pathname match prefix. Only full pathname elements are matched, so a path like /foo is not considered a prefix of /foobar, only of /foo/bar.

This call does no blocking i/o, as it works purely on names. As such it can sometimes return `False` even if file is inside a prefix (from a filesystem point of view), because the prefix of file is an alias of prefix.

### gio.File.has_uri_scheme

        def has_uri_scheme(uri_scheme)

`uri_scheme` : | a string containing a URI scheme.
Returns : | `True` if `gio.File`'s backend supports the given URI scheme, `False` if URI scheme is `None`, not supported, or `gio.File` is invalid.

The `has_uri_scheme`() method checks to see if a `gio.File` has a given URI scheme.

This call does no blocking i/o.

### gio.File.is_native

        def is_native()

Returns : | `True` if file is native.

The `is_native`() method checks to see if a file is native to the platform.

A native file s one expressed in the platform-native filename format, e.g. "C:\Windows" or "/usr/bin/". This does not mean the file is local, as it might be on a locally mounted remote filesystem.

On some systems non-native files may be available using the native filesystem via a userspace filesystem (FUSE), in these cases this call will return `False`, but `gio.File.get_path`() will still return a native path.

This call does no blocking i/o.

### gio.File.load_contents

        def load_contents(cancellable=None)

`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a three tuple containing the contents of the file, the length of the contents of the file and the current entity tag for the file.

The `load_contents`() method loads the content of the file into memory. The data is always zero-terminated, but this is not included in the resultant length.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

### gio.File.load_contents_async

        def load_contents_async(callback, cancellable=None, user_data=None)

`callback` : | a GAsyncReadyCallback to call when the request is satisfied.
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
`user_data` : | the data to pass to callback function.

For more details, see `gio.File.load_contents`() which is the synchronous version of this call.

When the load operation has completed, callback will be called with user data. To finish the operation, call `gio.File.load_contents_finish`() with the GAsyncResult returned by the callback.

### gio.File.load_contents_finish

        def load_contents_finish(result)

`result` : | a `gio.AsyncResult`.
Returns : | a three tuple containing the contents of the file, the length of the contents of the file and the current entity tag for the file.

The `load_contents_finish`() method finishes an asynchronous find mount started with `gio.File.load_contents_async`().

### gio.File.make_directory

        def make_directory(cancellable=None)

`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | `True` on successful creation, `False` otherwise.

The `make_directory`() method creates a directory. Note that this will only create a child directory of the immediate parent directory of the path or URI given by the `gio.File`. To recursively create directories, see `gio.File.make_directory_with_parents`(). This function will fail if the parent directory does not exist, setting error to gio.ERROR_NOT_FOUND. If the file system doesn't support creating directories, this function will fail, setting error to gio.ERROR_NOT_SUPPORTED.

For a local `gio.File` the newly created directory will have the default (current) ownership and permissions of the current process.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

### gio.File.make_directory_with_parents

        def make_directory_with_parents(cancellable=None)

`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | `True` if all directories have been successfully created, `False` otherwise.

The `make_directory_with_parents`() method creates a directory and any parent directories that may not exist similar to 'mkdir -p'. If the file system does not support creating directories, this function will fail, setting error to gio.ERROR_NOT_SUPPORTED.

For a local `gio.File` the newly created directories will have the default (current) ownership and permissions of the current process.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

### gio.File.make_symbolic_link

        def make_symbolic_link(symlink_value, cancellable=None)

`symlink_value` : | a string with the value of the new symlink.
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | `True` on the creation of a new symlink, `False` otherwise.

The `make_symbolic_link`() method creates a symbolic link.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

### gio.File.monitor

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

### gio.File.mount_enclosing_volume

        def mount_enclosing_volume(mount_operation, callback, flags=gio.FILE_COPY_NONE, cancellable=None, user_data=None)

`mount_operation` : | a `gio.MountOperation` or `None` to avoid user interaction.
`callback` : | a GAsyncReadyCallback to call when the request is satisfied, or `None`.
`flags` : | a set of Gio Mount Mount Flags Constants
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
`user_data` : | the data to pass to the progress callback function.

The `mount_enclosing_volume`() method starts a mount_operation, mounting the volume that contains the file location.

When this operation has completed, callback will be called with user_user data, and the operation can be finalized with `gio.File.mount_enclosing_volume_finish`().

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

### gio.File.mount_enclosing_volume_finish

        def mount_enclosing_volume_finish(result)

`result` : | a `gio.AsyncResult`.
Returns : | `True` if successful. If an error has occurred, this function will return `False` and set error appropriately if present.

The `mount_enclosing_volume_finish`() method finishes an asynchronous find mount started with `gio.File.mount_enclosing_volume`().

### gio.File.mount_mountable

        def mount_mountable(mount_operation, callback, flags=gio.FILE_COPY_NONE, cancellable=None, user_data=None)

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

### gio.File.mount_mountable_finish

        def mount_mountable_finish(result)

`result` : | a `gio.AsyncResult`.
Returns : | a `gio.File` or `None` on error.

The `mount_mountable_finish`() method finishes an asynchronous find mount started with `gio.File.mount_mountable`().

`destination` : | destination `gio.File`.
`progress_callback` : | function to callback with progress information.
`flags` : | a set of Gio File Copy Flags Constants
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
`user_data` : | the data to pass to the progress callback function.
Returns : | `True` on success, `False` otherwise.

The `move`() method tries to move the file or directory source to the location specified by destination. If native move operations are supported then this is used, otherwise a copy + delete fallback is used. The native implementation may support moving directories (for instance on moves inside the same filesystem), but the fallback code does not.

If the flag gio.FILE_COPY_OVERWRITE is specified an already existing destination file is overwritten.

If the flag gio.FILE_COPY_NOFOLLOW_SYMLINKS is specified then symlinks will be copied as symlinks, otherwise the target of the source symlink will be copied.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

If progress_callback is not `None`, then the operation can be monitored by setting this to a GFileProgressCallback function. progress_callback_data will be passed to this function. It is guaranteed that this callback will be called after all data has been transferred with the total number of bytes copied during the operation.

If the source file does not exist then the gio.ERROR_NOT_FOUND error is returned, independent on the status of the destination.

If gio.FILE_COPY_OVERWRITE is not specified and the target exists, then the error gio.ERROR_EXISTS is returned.

If trying to overwrite a file over a directory the gio.ERROR_IS_DIRECTORY error is returned. If trying to overwrite a directory with a directory the gio.ERROR_WOULD_MERGE error is returned.

If the source is a directory and the target does not exist, or gio.FILE_COPY_OVERWRITE is specified and the target is a file, then the gio.ERROR_WOULD_RECURSE error may be returned (if the native move operation isn't available).

### gio.File.query_default_handler

        def query_default_handler(cancellable=None)

`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a `gio.AppInfo` if the handle was found, `None` if there were errors.

### gio.File.query_exists

        def query_exists(cancellable=None)

`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | `True` if the file exists (and can be detected without error), `False` otherwise (or if cancelled).

The `query_exists`() method is an tility function to check if a particular file exists. This is implemented using `gio.File.query_info`() and as such does blocking I/O.

Note that in many cases it is racy to first check for file existence and then execute something based on the outcome of that, because the file might have been created or removed in between the operations. The general approach to handling that is to not check, but just do the operation and handle the errors as they come.

As an example of race-free checking, take the case of reading a file, and if it doesn't exist, creating it. There are two racy versions: read it, and on error create it; and: check if it exists, if not create it. These can both result in two processes creating the file (with perhaps a partially written file as the result). The correct approach is to always try to create the file with `gio.File.create`() which will either atomically create the file or fail with a gio.ERROR_EXISTS error.

However, in many cases an existence check is useful in a user interface, for instance to make a menu item sensitive/insensitive, so that you don't have to fool users that something is possible and then just show and error dialog. If you do this, you should make sure to also handle the errors that can happen due to races when you execute the operation.

### gio.File.query_file_type

        def query_file_type(flags=gio.FILE_MONITOR_NONE, cancellable=None)

`flags` : | a Gio File Query Info Flags Constants
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | Gio File Type Constants

The `query_file_type`() method it's an utility function to inspect the Gio File Query Info Flags Constants of a file. This is implemented using `gio.File.query_info`() and as such does blocking I/O.

The primary use case of this method is to check if a file is a regular file, directory, or symlink.

### gio.File.query_filesystem_info

        def query_filesystem_info(attributes, cancellable=None)

`attributes` : | an attribute query string.
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a `gio.FileInfo` or `None` if there was an error.

The `query_filesystem_info`() method it's similar to `gio.File.query_info`(), but obtains information about the filesystem the file is on, rather than the file itself. For instance the amount of space available and the type of the filesystem.

The attribute value is a string that specifies the file attributes that should be gathered. It is not an error if it's not possible to read a particular requested attribute from a file - it just won't be set. attribute should be a comma-separated list of attribute or attribute wildcards. The wildcard "*" means all attributes, and a wildcard like "fs:*" means all attributes in the fs namespace. The standard namespace for filesystem attributes is "fs". Common attributes of interest are gio.FILE_ATTRIBUTE_FILESYSTEM_SIZE (the total size of the filesystem in bytes), gio.FILE_ATTRIBUTE_FILESYSTEM_FREE (number of bytes available), and gio.FILE_ATTRIBUTE_FILESYSTEM_TYPE (type of the filesystem).

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

If the file does not exist, the gio.ERROR_NOT_FOUND error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

### gio.File.query_filesystem_info_async

For more details, see `query_filesystem_info`() which is the synchronous version of this call.

When the operation is finished, callback will be called. You can then call `gio.File.query_filesystem_info_finish`() to get the result of the operation.

### gio.File.query_filesystem_info_finish

        def query_filesystem_info_finish(result)

`result` : | a `gio.AsyncResult`.
Returns : | a `gio.FileInfo` or `None` if an error occurred.

The `query_filesystem_info_finish`() method finishes an asynchronous copy operation started with `gio.File.query_filesystem_info_async`().

### gio.File.query_filesystem_info

        def query_info(attributes, flags=gio.FILE_QUERY_INFO_NONE, cancellable=None)

`attributes` : | an attribute query string.
`flags` : | a Gio File Query Info Flags Constants
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a `gio.FileInfo` for the given file or `None` if there was an error.

The `query_info`() method gets the requested information about specified file. The result is a `gio.FileInfo` object that contains key-value attributes (such as the type or size of the file).

The attribute value is a string that specifies the file attributes that should be gathered. It is not an error if it's not possible to read a particular requested attribute from a file - it just won't be set. attribute should be a comma-separated list of attribute or attribute wildcards. The wildcard "*" means all attributes, and a wildcard like "standard::*" means all attributes in the standard namespace. An example attribute query be "standard::*,owner::user". The standard attributes are available as defines, like gio.FILE_ATTRIBUTE_STANDARD_NAME.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

For symlinks, normally the information about the target of the symlink is returned, rather than information about the symlink itself. However if you pass gio.FILE_QUERY_INFO_NOFOLLOW_SYMLINKS in flags the information about the symlink itself will be returned. Also, for symlinks that point to non-existing files the information about the symlink itself will be returned.

If the file does not exist, the gio.ERROR_NOT_FOUND error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

### gio.File.query_info_async

        def query_settable_attributes(cancellable=None)

`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a list of `gio.FileAttributeInfo` describing the settable attributes.

The `query_settable_attributes`() method obtain the list of settable attributes for the file.

Returns the type and full attribute name of all the attributes that can be set on this file. This doesn't mean setting it will always succeed though, you might get an access failure, or some specific file may not support a specific attribute.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

### gio.File.query_writable_namespace

        def query_writable_namespace(cancellable=None)

`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a list of `gio.FileAttributeInfo` describing the writable namespaces.

The `query_writable_namespace`() method obtain the list of attribute namespaces where new attributes can be created by a user. An example of this is extended attributes (in the "xattr" namespace).

### gio.File.read

        def read(cancellable=None)

`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a `gio.FileInputStream` or `None` on error.

The `read`() method opens a file for reading. The result is a `gio.FileInputStream` that can be used to read the contents of the file.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

If the file does not exist, the gio.ERROR_NOT_FOUND error will be returned. If the file is a directory, the gio.ERROR_IS_DIRECTORY error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

### gio.File.read_async

        def read_async(callback, io_priority=glib.PRIORITY_DEFAULT, cancellable=None, user_data=None)

`callback` : | a GAsyncReadyCallback to call when the request is satisfied.
`io_priority` : | the Glib Priority Constants of the request.
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
`user_data` : | the data to pass to callback function.

The `read_async`() method asynchronously opens file for reading.

For more details, see `read`() which is the synchronous version of this call.

When the operation is finished, callback will be called. You can then call `gio.File.read_finish`() to get the result of the operation.

### gio.File.read_finish

        def read_finish(result)

`result` : | a `gio.AsyncResult`.
Returns : | a `gio.FileInputStream` file or `None` if an error occurred.

The `read_finish`() method finishes an asynchronous copy operation started with `gio.File.read_async`().

### gio.File.replace

        def replace(etag, make_backup, flags=gio.FILE_CREATE_NONE, cancellable=None)

`etag` : | an optional entity tag for the current `gio.File`, or `None` to ignore.
`make_backup` : | `True` if a backup should be created.
`flags` : | a set of Gio File Create Flags Constants
`cancellable` : | optional `gio.Cancellable` object, `None` to ignore.
Returns : | a `gio.FileOutputStream` or `None` on error.

The `replace`() method returns an output stream for overwriting the file, possibly creating a backup copy of the file first. If the file doesn't exist, it will be created.

This will try to replace the file in the safest way possible so that any errors during the writing will not affect an already existing copy of the file. For instance, for local files it may write to a temporary file and then atomically rename over the destination when the stream is closed.

By default files created are generally readable by everyone, but if you pass gio.FILE_CREATE_PRIVATE in flags the file will be made readable only to the current user, to the level that is supported on the target filesystem.

If cancellable is not `None`, then the operation can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error gio.ERROR_CANCELLED will be returned.

If you pass in a non-`None` etag value, then this value is compared to the current entity tag of the file, and if they differ an gio.ERROR_WRONG_ETAG error is returned. This generally means that the file has been changed since you last read it. You can get the new etag from `gio.FileOutputStream.get_etag`() after you've finished writing and closed the GFileOutputStream. When you load a new file you can use `gio.FileInputStream.query_info`() to get the etag of the file.

If make_backup is `True`, this function will attempt to make a backup of the current file before overwriting it. If this fails a gio.ERROR_CANT_CREATE_BACKUP error will be returned. If you want to replace anyway, try again with make_backup set to `False`.

If the file is a directory the gio.ERROR_IS_DIRECTORY error will be returned, and if the file is some other form of non-regular file then a gio.ERROR_NOT_REGULAR_FILE error will be returned. Some file systems don't allow all file names, and may return an gio.ERROR_INVALID_FILENAME error, and if the name is to long gio.ERROR_FILENAME_TOO_LONG will be returned.
