       filesystems  -  Linux  filesystem  types:  ext, ext2, ext3, ext4, hpfs,
       iso9660, JFS, minix, msdos, ncpfs nfs, ntfs, proc, Reiserfs, smb, sysv,
       umsdos, vfat, XFS, xiafs,


       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  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                 been completely superseded  by  the  second  version  of  the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

       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

                 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

       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 64MB partition size limit, short filenames, and a
                 single  timestamp.   It  remains  useful for floppies and RAM

       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

       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 ⟨⟩.

       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.

                 To use smb fs, you need a special mount program, which can be
                 found  in the ksmbfs package, found at ⟨

       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 DOS 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.
