NAME
filesystems - Linux filesystem types: minix, ext, ext2, ext3, xia, msdos, umsdos, vfat, proc, nfs, iso9660, hpfs,
sysv, smb, ncpfs
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. If you need a currently unsupported one, insert the corresponding
module or recompile the kernel.
In order to use a filesystem, you have to mount it, see mount(8) for the mount command, and for the available
mount options.
Below a short description of a few of the available filesystems.
minix is the filesystem used in the Minix operating system, the first to run under Linux. It has a number of
shortcomings: a 64MB partition size limit, short filenames, a single time stamp, etc. It remains useful
for floppies and RAM disks.
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 It has been completely superseded by the second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 file system (ext). ext2 offers
the best performance (in terms of speed and CPU usage) of the filesystems supported under Linux.
ext3 is a journaling version of the ext2 filesystem. It is easy to switch back and forth between ext2 and ext3.
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 xia filesystem is no longer
actively developed or maintained. It was removed from the kernel in 2.1.21.
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.
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.
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).
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.
hpfs is the High Performance Filesystem, used in OS/2. This filesystem is read-only under Linux due to the
lack of available documentation.
sysv is an implementation of the SystemV/Coherent filesystem for Linux. It implements all of Xenix FS,
SystemV/386 FS, and Coherent FS.
nfs is the network filesystem used to access disks located on remote computers.
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
ftp://sunsite.unc.edu/pub/Linux/system/Filesystems/smbfs.
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.
