The 32-bit version of the FAT file system. In wide use on PCs that run Windows 95/98, FAT32 was introduced with the OEM Service Release 2 (OSR2) version of Windows 95 in 1996. It supports larger disk partitions and file sizes and has more safeguards than the earlier FAT (FAT16). In the event of disk failure, FAT32 can relocate the root directory on the disk and use the backup copy of the FAT table. FAT32 also reduced cluster waste (see cluster). Starting with Windows NT, FAT32 was superseded by NTFS. See exFAT, NTFS and FAT.
