    i just bought a new Kingston DT108 flash drive formatted to FAT32 and was able to transfer a 4.3gb video file without any problems. Why?

    :confused:

    No. You'll need to reformat it to something newer then FAT32.

    Then you drive isn't formatted with FAT32. FAT32 has a hard limit of 4.0G. It cannot be overridden on any operating system.

    That's due to the difference between binary and decimal GB. In decimal, 4GB is 4.0 billion bytes, whereas in binary, 4GB is equal to 4.3 billion bytes.

    A binary KB equals 1024 bytes, so 1024 x 1024 x 1024 x 4 equals 4.295 billion, rounded to 4.3. The file size is stated in decimal GB, but the actual file structure is in binary.
