Linux жүйесіндегі FAT файлдық жүйесінің форматтары

Widely used Linux filesystem format
Linux has several filesystem drivers for the File Allocation Table (FAT) filesystem format. These are commonly known by the names used in the mount command to invoke particular drivers in the kernel: , , and .

Most of the major Linux distributions, including RedHat, SuSE, and Debian, do not employ to permit installation of Linux on a FAT disc volume. A few distributions do, however. These include distributions such as Phat Linux, which installs in C:\PHAT on DOS by unpacking a ZIP file and is booted by running a COMMAND. COM script named LINUX. BAT, UVFAT, an extension of UMSDOS to use the Windows data structures for long filenames instead of its own, was discontinued before release. They should work in 2.4. x kernels. Earlier Linux distributions which used UMSDOS are MuLinux, Monkey Linux and Winlinux 2000.

All of the Linux filesystem drivers support all three FAT types, namely FAT12, FAT16 and FAT32. Where they differ is in the provision of support for long filenames, beyond the 8.3 filename structure of the original FAT filesystem format, and in the provision of Unix file semantics that do not exist as standard in the FAT filesystem format such as file permissions.

A modern equivalent of UMSDOS is POSIX Overlay Filesystem It works in FUSE.
