The Gnome Virtual File System ( GVfs for short ) is a network-transparent virtual file system for the GIMP-Toolkit , which enables access to files of various network protocols . GVfs is a further development of the earlier "GnomeVFS", which was developed for the Gnome desktop environment .

more details

The processes communicate with GVfs via D-Bus , which consists of a main system service (the daemon gvfsd ) and other services for various protocols. A separate binary protocol is used for file transfers. Supported network interfaces are e.g. B. SFTP , FTP , NFS , DAV , SMB , OBEX -FTP (Bluetooth cell phones) and from version 1.15.2 MTP (smartphones, digital cameras, MP3 players etc.). With GVfs, login data can be used throughout the session so that they do not have to be entered again for each application used. GNOME version 2.22.0 and later includes GVfs.

GVfs uses its own interface instead of defining and using a general POSIX interface for communication between the virtual file system and the application. GVfs can only be used via GIO , whose programming interface is documented.

Demon task
Main daemons
gvfsd The main daemon gvfsd is started automatically by programs that integrate GIO if it is not already running. Its primary task is to start required daemons. It makes the name "org.gtk.vfs.Daemon" available on the session bus.
gvfsd-fuse maintains an integration point to make the back-ends available for programs that do not use GIO.
gvfsd-metadata Serializes the writing of metadata . Is z. B. used by Nautilus .
