The FAT16 file system is an older version of the File Allocation Table system. The newer FAT version is FAT32, which is recommended over the FAT16 system unless compatibility with older hardware forces FAT16 use. Formatting your USB flash drive in Windows 7 imposes a 4GB limit on the USB drive's size when using FAT16. If your USB flash drive is larger than that, Windows will not even list FAT16 as a formatting option.
