Gio virtual file system
GIO provides a VFS API to GLib applications. It includes a 'local' implementation using POSIX. gvfs provides implementations that go beyond that and allow to access files and storage using many protocols, such as ftp, http, sftp, dav, obexftp, etc. It also provides support for trash folders, for cd burning and for monitoring interesting devices and volumes on the computer.
Applications use gvfs indirectly, by means of GIO loading the gvfs module that implements the GIO extension points. The gvfs support for volume monitoring is included in a separate loadable module.
The actual gvfs implementation is distributed over a number of processes. None of these are expected to be started from the commandline, except for debugging purposes.
Main processes:
gvfsd - the main gvfs daemon
gvfs-fuse-daemon - mounts gvfs as a fuse filesystem
gvfsd-metadata - writes gvfs metadata
Volume monitors:
gvfs-udisks2-volume-monitor - a udisks-based volume monitor
gvfs-afc-volume-monitor - a volume monitor for Apple iPhone/iPod Touch devices
Mount backends:
gvfsd-afc - mounts iPhone/iPod touch volumes
gvfsd-afp - mounts Apple Filing Protocol volumes
gvfsd-afp-browse - browses Apple Filing Protocol volumes
gvfsd-archive - mounts archive files in various formats
gvfsd-burn - provides a location for burning CDs
gvfsd-cdda - mounts audio CDs
gvfsd-computer - provides computer://
gvfsd-dav - mounts DAV filesystems
gvfsd-dnssd - browses dnssd
gvfsd-ftp - mounts over FTP
gvfsd-http - mounts over HTTP
gvfsd-localtest - a test backend
gvfsd-network - provides network://
gvfsd-obexftp - mounts over obexftp
gvfsd-recent - provides recent://
gvfsd-sftp - mounts over sftp
gvfsd-smb - mounts Windows Shares Filesystem volumes
gvfsd-smb-browse - browses Windows Shares Filesystem volumes
gvfsd-trash - provides trash://
GIO_USE_VFS
