Several versions of files systems have been developed for PCs based on the amount of locations that can be uniquely addressed by the processor. These locations are stored in a File Allocation Table (FAT) with the number of bits that can be used to address files on the hard drive.
Windows 98 and Windows Me offer two choices for file systems: FAT16 and FAT32.
- FAT16 is supported by all Windows versions and MS-DOS.
- FAT32 is supported by Windows 9x, Me, 2000 and XP.
Windows NT supports FAT16 and NTFS (a more secure file management system that allows individual files and folders to be accessible by named individuals or groups). Windows XP supports FAT16, FAT32 and NTFS.
