* @short_description: Functions for working with GIO
* @Title: Filesystem utilities
*
* The functions and objects described here make working with GTK+ and
* GIO more convenient.
*
* #GtkMountOperation is needed when mounting volumes:
* It is an implementation of #GMountOperation that can be used with
* GIO functions for mounting volumes such as
* g_file_mount_enclosing_volume(), g_file_mount_mountable(),
* g_volume_mount(), g_mount_unmount_with_operation() and others.
*
* When necessary, #GtkMountOperation shows dialogs to ask for
* passwords, questions or show processes blocking unmount.
*
* gtk_show_uri() is a convenient way to launch applications for URIs.
*
* Another object that is worth mentioning in this context is
* #GdkAppLaunchContext, which provides visual feedback when lauching
* applications.
