FAT16 file system <FAT16>

Field:
Windows > File system > FAT16 file system

The file system which is utilized with Windows 3.1 and Windows 95. Dividing the disk 16 powers (=65536) into the small unit of 2, it manages. The territory to of maximum 2GB can be managed. When the disk of the capacity which exceeds 2GB is utilized, it is necessary to divide into the plural territories (partition).

FAT32 <FAT32 file system>

Full spelling: File Allocation Table 32
Field:
Windows > File system > FAT32

After the Windows 95 OSR 2.0 and the file system which is utilized with Windows 98/Me. Dividing the disk 32 powers (= approximately 4,200,000,000) into the small unit of 2, it manages. The territory to of maximum 2TB can be managed. When the disk of capacity below 2GB which can be managed even with FAT16 is managed with FAT32, management efficiency increasing, because the wasteful territory decreases, the disk can be utilized effectively. FAT32 is used but, can also use with Windows 2000/XP and the like mainly with Windows 98/Me, (you cannot use with Windows NT).

FAT32X

Reading: Fat [ji] [yu] sea urchin x
Field:
Windows > File system > FAT32X

The FAT32 partition which appoints the specific sector inside partition with LBA system.

With the usual FAT32 partition CHS system is used for disk access, but with CHS because it can access only the disk to with respect to 8GB specification, with the FAT32 partition which includes the territory where it exceeds 8GB from the forefront of the disk even a little, FAT32X which appoints the sector inside partition with LBA is used.

In addition, when the partition which uses the end of HDD was drawn up with FAT32, because with CHS system the designated impossibility the part develops excessively in the final part, FDISK draws up the FAT32X partition which uses the LBA system which can use this part effectively. Therefore, there are also times when disk size FAT32X is drawn up on the hard disk under 8GB.

The territory to of maximum 2TB can be managed. When the disk of capacity below 2GB which can be managed even with FAT16 is managed with FAT32, management efficiency increasing, because the wasteful territory decreases, the disk can be utilized effectively.

FAT64

Field:
Windows > File system > FAT64

At one of the file systems which with Windows NT/Windows 2000/Windows XP can be used, the extended system of FAT16.

With FAT16 cluster size is restricted to 32KB, but with FAT64 the cluster of 64KB can be handled. Other specification being completely identical with FAT16, is 4GB where also maximum capacity around the partition is exactly 2 times that FAT16.

“FAT16” “FAT32” is derived from managing the number of clusters respectively at 16 bit value and 32 bit value, but it is not the case that “FAT64” means the fact that cluster size is 64KB, has managed at 64 bit value.

As for the corresponding function to FAT64 because it is not included in only the NT kernel, from Windows NT/2000 afterwards, Windows 98/Windows Me which uses the 9x kernel cannot handle FAT64 even with Windows which release is done.
