DESCRIPTION

       When,  as  is  customary,  the  proc  filesystem  is  mounted  on  /proc,  you  can  find  in  the   file
       /proc/filesystems which filesystems your kernel currently supports; see proc(5) for more details.  If you
       need a currently unsupported filesystem, insert the corresponding module or recompile the kernel.

       In order to use a filesystem, you have to mount it; see mount(8).

       Below a short description of the available or historically available filesystems  in  the  Linux  kernel.
       See kernel documentation for a comprehensive description of all options and limitations.

       ext       is  an  elaborate  extension of the minix filesystem.  It has been completely superseded by the
                 second version of the extended filesystem (ext2) and has  been  removed  from  the  kernel  (in
                 2.1.21).

       ext2      is  the  high  performance  disk  filesystem used by Linux for fixed disks as well as removable
                 media.  The second extended filesystem was designed as an extension of the extended  filesystem
                 (ext).  See ext2 (5).

       ext3      is  a  journaling  version of the ext2 filesystem.  It is easy to switch back and forth between
                 ext2 and ext3.  See ext3 (5).

       ext4      is a set of upgrades to ext3 including substantial performance  and  reliability  enhancements,
                 plus large increases in volume, file, and directory size limits.  See ext4 (5).

       hpfs      is the High Performance Filesystem, used in OS/2.  This filesystem is read-only under Linux due
                 to the lack of available documentation.

       iso9660   is a CD-ROM filesystem type conforming to the ISO 9660 standard.

                 High Sierra
                        Linux supports  High  Sierra,  the  precursor  to  the  ISO  9660  standard  for  CD-ROM
                        filesystems.  It is automatically recognized within the iso9660 filesystem support under
                        Linux.

                 Rock Ridge
                        Linux also supports the System Use Sharing Protocol records specified by the Rock  Ridge
                        Interchange  Protocol.   They  are  used  to  further  describe the files in the iso9660
                        filesystem to a UNIX host, and provide information  such  as  long  filenames,  UID/GID,
                        POSIX  permissions,  and  devices.   It  is  automatically recognized within the iso9660
                        filesystem support under Linux.

       JFS       is a journaling filesystem, developed by IBM, that was integrated into Linux in kernel 2.4.24.

       minix     is the filesystem used in the Minix operating system, the first to run under Linux.  It  has  a
                 number  of  shortcomings, including a 64 MB partition size limit, short filenames, and a single
                 timestamp.  It remains useful for floppies and RAM disks.

       msdos     is the filesystem used by DOS, Windows, and some OS/2 computers.  msdos  filenames  can  be  no
                 longer than 8 characters, followed by an optional period and 3 character extension.

       ncpfs     is a network filesystem that supports the NCP protocol, used by Novell NetWare.

                 To  use  ncpfs,  you  need  special  programs, which can be found at ⟨ftp://linux01.gwdg.de/pub
                 /ncpfs⟩.

       nfs       is the network filesystem used to access disks located on remote computers.

       ntfs      replaces Microsoft Window's FAT filesystems (VFAT, FAT32).  It  has  reliability,  performance,
                 and space-utilization enhancements plus features like ACLs, journaling, encryption, and so on.

       proc      is  a  pseudo  filesystem  which  is used as an interface to kernel data structures rather than
                 reading and interpreting /dev/kmem.  In particular, its files do  not  take  disk  space.   See
                 proc(5).

       Reiserfs  is  a  journaling filesystem, designed by Hans Reiser, that was integrated into Linux in kernel
                 2.4.1.

       smb       is a network filesystem that supports the SMB protocol, used by Windows for Workgroups, Windows
                 NT, and Lan Manager.  See ⟨https://www.samba.org/samba/smbfs/⟩.

       sysv      is  an implementation of the SystemV/Coherent filesystem for Linux.  It implements all of Xenix
                 FS, SystemV/386 FS, and Coherent FS.

       umsdos    is an extended DOS filesystem used by Linux.  It adds capability for long  filenames,  UID/GID,
                 POSIX  permissions,  and  special files (devices, named pipes, etc.)  under the DOS filesystem,
                 without sacrificing compatibility with DOS.

       vfat      is an extended FAT filesystem used by Microsoft  Windows95  and  Windows  NT.   vfat  adds  the
                 capability to use long filenames under the MSDOS filesystem.

       XFS       is a journaling filesystem, developed by SGI, that was integrated into Linux in kernel 2.4.20.

       xiafs     was  designed and implemented to be a stable, safe filesystem by extending the Minix filesystem
                 code.  It provides the basic most requested  features  without  undue  complexity.   The  xiafs
                 filesystem  is  no  longer actively developed or maintained.  It was removed from the kernel in
                 2.1.21.
