About FAT16 File System

As you might know, there are 8-bit FAT, FAT12, FAT16, and FAT32. On Windows PCs, the FAT file system usually stands for FAT12 and FAT16. The FAT16 file system was released in 1984 to make the disk usage more efficient. The boundary between FAT12 and FAT16 is 16 MB. So, if the partition is larger than 16MB, it is FAT16 actually. If the partition is smaller than 16MB, it is FAT12.

Besides, the maximum size of FAT16 is 4GB. That’s to say if you want to create or format a drive larger than 4GB, the “FAT16/FAT” option will not be available. In this case, how to format USB to FAT16 on Windows 10/8/7? Let’s keep reading.
