+.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.
+.PP
+If you need a currently unsupported filesystem, insert the corresponding
+kernel module or recompile the kernel.
+.PP
+In order to use a filesystem, you have to
+.I mount
+it; see
+.BR mount (2)
+and
+.BR mount (8).
+.PP
+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+It has been completely superseded by the second version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 9660 standard.
+.RS
+.TP
+.B "High Sierra"
+Linux supports High Sierra, the precursor to the ISO 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.
