File Allocation Table (FAT) is a computer file system architecture and a family of industry-standard file systems utilizing it. The FAT file system is a legacy file. Deletes the file table and the root directory of a previously formatted volume but does not perform a sector by sector scan for bad areas.

Choosing the file system to use on a Windows XP system is seldom easy, and frequently it's not just a one time decision. If you have ever tried to format a USB thumb drive or memory stick, you may have noticed that the only file system options you have are FAT and FAT32.
It is, however, supported for compatibility reasons by nearly all currently developed operating systems for personal computers and many mobile devices and embedded systems, and thus is a well- suited format for data exchange between computers and devices of almost any type and age from 1. Originally designed in 1. FAT was soon adapted and used almost universally on hard disks throughout the DOS and Windows 9x eras for two decades. The FAT standard has also been expanded in other ways while generally preserving backward compatibility with existing software.
With the introduction of more powerful computers and operating systems, as well as the development of more complex file systems for them, FAT is no longer the default file system for usage on Microsoft Windows computers. FAT is the standard file system for digital cameras per the DCF specification. Overview. 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, 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. Originally designed as an 8- bit file system, the maximum number of clusters has been significantly increased as disk drives have evolved, and so the number of bits used to identify each cluster has grown. The successive major variants of the FAT format are named after the number of table element bits: 1.
FAT1. 2), 1. 6 (FAT1. FAT3. 2). Except for the original 8- bit FAT precursor, each of these variants is still. The FAT standard has also been expanded in other ways while generally preserving backward compatibility with existing software. The FAT file system has a long history (over three decades) of usage on desktops and portable computers, and it is frequently used in embedded solutions.
FAT offers reasonably good performance and robustness, even in very light- weight implementations. This also makes it a useful format for solid- statememory cards and a convenient way to share data between operating systems. FAT file systems are the default file system for removable media (with the exception of CDs and DVDs) and as such are commonly found on floppy disks, super- floppies, memory and flash memory cards or USB flash drives and are supported by most portable devices such as PDAs, digital cameras, camcorders, media players, or mobile phones.
While FAT1. 2 is omnipresent on floppy disks, FAT1. FAT3. 2 are typically found on the larger media. FAT was also commonly used on hard disks throughout the DOS and Windows 9x eras, but its use on hard drives has declined since the introduction of Windows XP, which primarily uses the newer NTFS. FAT is still used in hard drives expected to be used by multiple operating systems, such as in shared Windows, GNU/Linux and DOS environments. Due to the widespread use of FAT- formatted media, many operating systems provide support for FAT through official or third- party file system handlers. For example, OS/2, GNU/Linux, Free. BSD and Be. OS provide built- in support for FAT, even though they also support more sophisticated file systems such as ext.
Mac OS 9 and mac. OS support FAT file systems on volumes other than the boot disk. Amiga. OS supports FAT through the Cross. DOS package. For many purposes, the NTFS file system is superior to FAT in terms of features and reliability; its main drawbacks are its complexity and the size overhead for small volumes as well as the very limited support by anything other than the NT- based versions of Windows, since the exact specification is a trade secret of Microsoft. The availability of NTFS- 3. G since mid- 2. 00. NTFS support in Unix- like operating systems, considerably alleviating this concern.
It is still not possible to use NTFS in DOS- like operating systems without third- party drivers, which in turn makes it difficult to use a DOS floppy for recovery purposes. Microsoft provided a Recovery Console to work around this issue, but for security reasons it severely limited what could be done through the Recovery Console by default. The movement of recovery utilities to boot CDs based on Bart. PE, Linux (with NTFS- 3.
G), or Win. PE is eroding this drawback, but the complexity of NTFS prevents its implementation in light- weight operating systems or most embedded systems. The DCF file system adopted by almost all digital cameras since 1. FAT1. 2, FAT1. 6, FAT3.
FAT mandatory for its physical layer in order to maximize platform interoperability. These standards cover FAT1. FAT1. 6 with only short 8.
VFAT are partially patented. In contrast to this, Microsoft typically no longer distinguishes between all three of them since the introduction of FAT3. FAT1. 2 and FAT1. This can sometimes lead to confusion if the actual type of the file system used is not mentioned or cannot be explicitly specified (e.
While technically the newer variant with 3. Volumes utilizing VFAT long- filenames can be read also by operating systems not supporting the VFAT extension, for as long as they support the underlying file system. Yet another cause for misconceptions stems from some apparent redundancy and possible ambiguity in the definition of FAT volumes.
The general type of file system (FAT1. FAT1. 6 or FAT3. 2) is determined by the width of the cluster entries in the FAT. Specific threshold values for the amount of clusters. Even though other properties such as the size of the volume, the count of sectors, the BPB format, the file system name in an EBPB, or - in case of partitioned media- the used partition ID may often seem to be well- suited distinguishing criteria as well, they cannot reliably be used to derive the file system type from in all scenarios. The FAT file system was also utilized in Microsoft's MDOS/MIDAS.
The Standalone Disk BASIC version supported three FATs. Reportedly, MIDAS was also prepared to support 1. FAT variants. While the size of directory entries was 1. Standalone Disk BASIC. PC DOS 1. 0, 3. 2- byte directory entries, 1 reserved sector)1.

The format used in Microsoft Standalone Disk BASIC's 8- bit file system precursor was not supported by QDOS. By August 1. 98. 0, QDOS had been renamed into 8. DOS already. Later in 1. DOS evolved into Microsoft's MS- DOS and IBMPC DOS. FAT1. 2 was used by several manufacturers with different physical formats, but a typical floppy disk at the time was 5.
Ki. B for both the system areas and files. The FAT1. 2 limitations exceeded this capacity by a factor of ten or more. The 3. 2 Mi. B limit was later circumvented using logical sectored FATs with logical sector sizes larger than 5. OEM versions of MS- DOS 3. FAT1. 6B became available with DOS 3.
By convention, all the control structures were organized to fit inside the first track, thus avoiding head movement during read and write operations, although this varied depending on the manufacturer and physical format of the disk. A limitation which was not addressed until much later (with FAT3.
The DOS formatting tool rejected such disks completely. Bad sectors were allowed only in the file data area and (since DOS 2.

B (FAT ID 0x. FD). DOS 1. 0. 0 and PC DOS 1. PC DOS 1. 1 added the last modified time. PC DOS 1. x file attributes included a hidden bit and system bit, with the remaining six bits undefined. At this time, DOS did not support a hierarchical file system, which was still acceptable, given that the number of files on a disk was typically not more than a few dozen. The PC XT was the first PC with a hard drive from IBM, and PC DOS 2.

Mi. B for 5. 12 byte sectors and 4 Ki. B clusters. The BIOS Parameter Block (BPB) was introduced with PC DOS 2. Cluster addresses were increased to 1.
However, the maximum possible number of sectors and the maximum (partition, rather than disk) size of 3. Mi. B did not change. Therefore, although cluster addresses were 1. FAT1. 6. A partition type. FAT1. 6 with less than 6. Mi. B for sector size 5. With the initial implementation of FAT1.
