       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.  There is also a legacy sysfs(2) system call (whose availability is controlled by
       the  CONFIG_SYSFS_SYSCALL kernel build configuration option since Linux 3.15) that enables
       enumeration of the currently available filesystem types regardless of  /proc  availability
       and/or sanity.

       If  you need a currently unsupported filesystem, insert the corresponding kernel module or
       recompile the kernel.

       In order to use a filesystem, you have to mount it; see mount(2) and mount(8).

       The following list provides a short description of the available or historically available
       filesystems  in  the  Linux  kernel.   See  the  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                 superseded  by the second version of the extended filesystem (ext2) and has been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 Linux 2.1.21).

       ext2      is a disk filesystem that was 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

       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

       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.
                 It was removed from the kernel in Linux 4.17.

                 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      is the filesystem native to Microsoft Windows NT, supporting 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 2.4.1.

       smb       is  a  network  filesystem that supports the SMB protocol, used by Windows.  See

       sysv      is an  implementation  of  the  System  V/Coherent  filesystem  for  Linux.   It
                 implements all of Xenix FS, System V/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.

       tmpfs     is  a  filesystem  whose  contents reside in virtual memory.  Since the files on
                 such filesystems typically reside in RAM, file access is  extremely  fast.   See

       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

       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 Linux 2.1.21.
