Just another reason why FAT was obsoleted by HPFS which in
turn was obsoleted by NTFS.

I'l bite:

I think I understant FAT systems.

But the only thing I "think" I know about the NTFS is that, effectively, the
system first makes a record of what it is about to do, then it does it, and
then it either erases the original record or somehow marks it.

SO: can someone "explain" the NTFS to me. (Please don't tell me to "look
it up.")
