-.SH NAME
-filesystems \- Linux filesystem types: ext, ext2, ext3, ext4, hpfs, iso9660,
-JFS, minix, msdos, ncpfs nfs, ntfs, proc, Reiserfs, smb, sysv, umsdos, vfat,
-XFS, xiafs
-.SH DESCRIPTION
-When, as is customary, the
-.B proc
-filesystem is mounted on
-.IR /proc ,
-you can find in the file
-.I /proc/filesystems
-which filesystems your kernel currently supports;
-see
-.BR proc (5)
-for more details.
-There is also a legacy
-.BR sysfs (2)
-system call (whose availability is controlled by the
-.\" commit: 6af9f7bf3c399e0ab1eee048e13572c6d4e15fe9
-.B CONFIG_SYSFS_SYSCALL
-kernel build configuration option since Linux 3.15)
-that enables enumeration of the currently available filesystem types
-regardless of
-.I /proc
-availability and/or sanity.
-.P
-If you need a currently unsupported filesystem, insert the corresponding
-kernel module or recompile the kernel.
-.P
-In order to use a filesystem, you have to
-.I mount
-it; see
-.BR mount (2)
-and
-.BR mount (8).
-.P
-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.
-.TP
-.B erofs
-is the Enhanced Read-Only File System, stable since Linux 5.4.
-.\" commit 47e4937a4a7ca4184fd282791dfee76c6799966a moves it out of staging
-See
-.BR erofs (5).
-.TP
-.B ext
-is an elaborate extension of the
-.B minix
-filesystem.
-It has been completely superseded by the second version
-of the extended filesystem
-.RB ( ext2 )
-and has been removed from the kernel (in Linux 2.1.21).
-.TP
-.B 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
-.RB ( ext ).
-See
-.BR ext2 (5).
-.TP
-.B ext3
-is a journaling version of the
-.B ext2
-filesystem.
-It is easy to
-switch back and forth between
-.B ext2
-and
-.BR ext3 .
-See
-.BR ext3 (5).
-.TP
-.B ext4
-is a set of upgrades to
-.B ext3
-including substantial performance and
-reliability enhancements,
-plus large increases in volume, file, and directory size limits.
-See
-.BR ext4 (5).
-.TP
-.B hpfs
-is the High Performance Filesystem, used in OS/2.
-This filesystem is
-read-only under Linux due to the lack of available documentation.
-.TP
-.B iso9660
-is a CD-ROM filesystem type conforming to the ISO/IEC\~9660 standard.
-.RS
-.TP
-.B "High Sierra"
-Linux supports High Sierra, the precursor to the ISO/IEC\~9660 standard for
-CD-ROM filesystems.
-It is automatically recognized within the
-.B iso9660
-filesystem support under Linux.
-.TP
-.B "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
-.B 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
-.B iso9660
-filesystem support under Linux.
-.RE
-.TP
-.B JFS
-is a journaling filesystem, developed by IBM,
-that was integrated into Linux 2.4.24.
-.TP
-.B 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.
-.TP
-.B msdos
-is the filesystem used by DOS, Windows, and some OS/2 computers.
-.B msdos
-filenames can be no longer than 8 characters, followed by an
-optional period and 3 character extension.
-.TP
-.B ncpfs
-is a network filesystem that supports the NCP protocol,
-used by Novell NetWare.
-It was removed from the kernel in Linux 4.17.
-.IP
-To use
-.BR ncpfs ,
-you need special programs, which can be found at
-.UR ftp://ftp.gwdg.de\:/pub\:/linux\:/misc\:/ncpfs
-.UE .
-.TP
-.B nfs
-is the network filesystem used to access disks located on remote computers.
-.TP
-.B ntfs
-is the filesystem native to Microsoft Windows NT,
-supporting features like ACLs, journaling, encryption, and so on.
-.TP
-.B proc
-is a pseudo filesystem which is used as an interface to kernel data
-structures rather than reading and interpreting
-.IR /dev/kmem .
-In particular, its files do not take disk space.
-See
-.BR proc (5).
-.TP
-.B Reiserfs
-is a journaling filesystem, designed by Hans Reiser,
-that was integrated into Linux 2.4.1.
-.TP
-.B smb
-is a network filesystem that supports the SMB protocol, used by
-Windows.
-See
-.UR https://www.samba.org\:/samba\:/smbfs/
-.UE .
-.TP
-.B 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.
-.TP
-.B 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.
-.TP
-.B 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
-.BR tmpfs (5).
-.TP
-.B vfat
-is an extended FAT filesystem used by Microsoft Windows95 and Windows NT.
-.B vfat
-adds the capability to use long filenames under the MSDOS filesystem.
-.TP
-.B XFS
-is a journaling filesystem, developed by SGI,
-that was integrated into Linux 2.4.20.
-.TP
-.B 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
-.B xiafs
-filesystem is no longer actively developed or maintained.
-It was removed from the kernel in Linux 2.1.21.
