I (maybe incorrectly) thought that some DOSes indeed kept the FAT completely in RAM. I'm a bit fuzzy on the details since I never looked too closely, so maybe I'm thinking of only really small disks. (Obviously not FAT32, but if FAT16 is max. 65535 files, would that fit? Arjay? )

Anyways, this is just another example of why we should have native support of ext2 or HPFS or whatever. (Linux gets 40+ FSes and we get only one, whee! It's a pity they don't help us more. If I weren't so dumb ....)
