On hard disks, DR DOS additionally accepts the swapped JMPS sequence starting with a NOP ( 0x90 0xEB 0x ), 17 whereas MS-DOSPC DOS do not. (See below for Atari ST compatibility.) The presence of one of these opstring patterns (in combination with a test for a valid media descriptor value at offset 0x015 ) serves as indicator to DOS 3.3 and higher that some kind of BPB is present (although the exact size should not be determined from the jump target since some boot sectors contain private boot loader data following the BPB), while for DOS 1.x (and some DOS 3.0) volumes, they will have to fall back to the DOS 1.x method to detect the format via the media byte in the FAT (in logical sector 1 ).

Today, FAT file systems are still commonly found on floppy disks, USB sticks, flash and other solid-state memory cards and modules, and many portable and embedded devices.

DCF implements FAT as the standard file system for digital cameras since 1998.

FAT is also utilized for the EFI system partition (partition type 0xEF ) in the boot stage of EFI -compliant computers.

These standards cover FAT12 and FAT16 with only short 8.3 filename support; long filenames with VFAT are partially patented.

According to Google Patents the status of Common name space for long and short filenames (US5758352A) was expired in 2019, which may mean that the patent has expired completely.

The table contains entries for each cluster, a contiguous area of disk storage.

Each entry contains either the number of the next cluster in the file, or else a marker indicating end of file, unused disk space, or special reserved areas of the disk.

The root directory of the disk contains the number of the first cluster of each file in that directory; the operating system can then traverse the FAT table, looking up the cluster number of each successive part of the disk file as a cluster chain until the end of the file is reached.

In much the same way, sub-directories are implemented as special files containing the directory entries of their respective files.

The successive major versions of the FAT format are named after the number of table element bits: 12 ( FAT12 ), 16 ( FAT16 ), and 32 ( FAT32 ).

Except for the original 8-bit FAT precursor, each of these variants is still in use.

The FAT standard has also been expanded in other ways while generally preserving backward compatibility with existing software.

It includes an area called the BIOS Parameter Block ( BPB ) which contains some basic file system information, in particular its type and pointers to the location of the other sections, and usually contains the operating systems boot loader code.

The Backup Boot Sector area consists of three logical sectors 6, 7, and 8 as well.

In some cases, Microsoft also uses sector 12 of the reserved sectors area for an extended boot loader.

In FAT12 and FAT16 they immediately follow the reserved sectors.

It is only used with FAT12 and FAT16, and imposes on the root directory a fixed maximum size which is pre-allocated at creation of this volume.

FAT32 stores the root directory in the Data Region, along with files and other directories, allowing it to grow without such a constraint.

CPM floppies typically came pre-formatted with a value of 0xE5; 11 by way of Digital Research 12 this value was also used on Atari ST formatted floppies.

The latter value is typically also used on ROM disks.

Some advanced formatting tools allow to configure the format filler byte.

Files are allocated in units of clusters, so if a 1 KB file resides in a 32 KB cluster, 31 KB are wasted.

The end of the last sector of each FAT copy can be unused if there are no corresponding clusters.

The total number of sectors (as noted in the boot record) can be larger than the number of sectors used by data (clusters sectors per cluster), FATs (number of FATs sectors per FAT), the root directory (na for FAT32), and hidden sectors including the boot sector: this would result in unused sectors at the end of the volume.

If a partition contains more sectors than the total number of sectors occupied by the file system it would also result in unused sectors, at the end of the partition, after the volume.

For partitioned devices such as hard drives, the first sector is the Master Boot Record defining partitions, while the first sector of partitions formatted with a FAT file system is again the Boot Sector.

On hard disks, DR DOS additionally accepts the swapped JMPS sequence starting with a NOP ( 0x90 0xEB 0x ), 17 whereas MS-DOSPC DOS do not.
