So i think i'll have to wait for more details, cause if all partitions are NTFS, i don't think he expanded one of these partitions to FAT, he can convert it back into a FAT (if already transformed from FAT to NTFS), i don't know but this is a little confused, i really think is better to wait for the details, cause now i can't confirm my previous response.
How is this expand what you talk about, and what he used to do it, i need to know to give the most better answer.
