Ok, a friend got caught by this... and deleting it really screwed up her computer. From what I've read, it shouldn't have become that screwed?
Her computer didn't even know where the Program Files folder was located.
I've replaced her missing sulfnbk.exe from Win98 with mine from Win98SE... then restored the long file names. Now there's a whole bunch of folders called variations of LFN3579.TMP, and I'm trying to rename them to the right names so that her computer can find information inside itself.
It's a bloody job.
Some were easy to find, but others... I haven't a clue what they should all be called...
Why did it screw up this computer so badly when others are fine?
