FAT file system

FAT (File Allocation Table) is a file system developed by Microsoft. It was used in DOS and Windows 9x/ME. Linux supports all versions of FAT using the VFAT kernel module.

Although FAT doesn’t provide the same performance as some more modern file systems, it has one great advantage: it is supported by most operating system. Because of it FATĀ is still the default file system on on floppy disks, USB flash drives, cell phones, and other types of removable storage.

FAT32 is the most recent version of FAT.
