@ Minuous:

>4Gb partitions is supported by dos. That is because dos only makes references to the logical blocks on the drive, not the bytes. In other words: A partition can be (block size) * 2^32 bytes big ((block size) * 2^31 if signed ints is used as with file offsets...).

With files it is bit different. Here it's the byte offset being used restricting file sizes to 2^31 - 1 bytes (again signed math -- eeww! 8^)
