FAT32 is called the reorganized edition. Windows XP contains a reorganized edition of the FAT file system. The FAT32 file system permits for a default group size as small as 4 KB, and contains support for EIDE hard disk sizes bigger than 2 GB.

• Microsoft Windows 2000, Windows Millennium Edition, Windows 98, and Windows 95 OSR2 also sustain the FAT32 file system.

• Microsoft Windows NT 4.0 does not sustain the FAT32 file system.

FAT32 characteristics

FAT32 presents the following improvements over previous executions of the FAT file system:

• FAT32 sustains drives up to 2 TB in size.

• FAT32 utilizes smaller groups i.e. 4KB clusters for drives up to 8 GB in size, resulting in a 10 to 15 % more proficient use of disk space comparative to large FAT or FAT16 drives. FAT32 utilizes space more capably

• FAT32 is more stretchy. File allocation table mirroring can be disabled, allowing a copy of the file allocation table other than the first one to be active. Additionally, The root folder on a FAT32 drive is an ordinary cluster chain, so it can be located anywhere on the drive. The earlier restrictions on the number of root folder entries no longer survive. These characteristics permit for dynamic resizing of FAT32 divisions.

• FAT32 is more strong. FAT32 can transfer the root folder and use the backup copy of the file distribution table instead of the default copy. Additionally, the boot record on FAT32 drives is expanded to include a backup copy of critical data structures. Therefore, FAT32 drives are less vulnerable to a single point of failure than existing FAT16 drives.
