FAT32 is the acronym for File Allocation Table and it denotes the 32-bit, low-level organization of files on floppy and hard disks. FAT32 is a 32-bit file system used by the OSR2 release of Windows 95 that avoids much of the wasted disk space inherent in the original 16-bit FAT, the file system used by DOS and the original Windows 95. FAT also cannot support hard disk larger than 2 GB, while FAT32 can handle such large disks with ease. On the other hand, no other operating system can access a disk that uses FAT32, not DOS, not Windows NT, and not even the original release of Windows 95.
