I've got a 500GB external drive formatted with exFAT (so it can be written by a mac and read by windows), there should be about 200GB free but right now there's only 60GB.

One folder is 187GB big, but in the properties window it says "size 187GB. Size on disk, 315GB". Why is this? Is it a limitation of exFAT or what? I've tried formatting it and i get the same result.

I kind of need a quick answer if anyone has any ideas.

If the disk on one partition or more?

Cluster size?
IIRC exFAT uses like 128K or something where NTFS is usually 4K.

If you have a crapload of small files, even a text file with one character would occupy 128 KB.

I don't know about the cluster size, I think i left it at "default" when i formatted it. What can i do about that though? From looking most of the files seem to be HD videos from a gopro (it's my friend's, i backed up his old one and i'm placing the files on his new one).

If NTFS uses 4096 and exfat 128KB would that cause problems?

The drive is formatted with 1 big partition.
