Description
since FAT filesystem support is do-able, why not exFAT? it's 64-bit.
it's probably going to be the next logical step for the next size up of usb stick. there are microsoft software limitations to FAT32 drives: it will not format a drive larger than 32GiB. http://jesusnjim.com/pc-repair/limitations.html
windows vista and 7 support exFAT I believe.
the chkdsk and autochk and defrag and autodefrag utilities (and whatever) should support the full 64 bits.
if the structure is based on unsigned 64-bit numbers, make real sure that you are using unsigned 64-bit numbers in the structures and filesystem and code. otherwise, you are going to run into trouble.
