I do now that you mentioned it. And there was an archive format starting with LZ* right? LZW? LZJ?
I mainly hit that one when downloading .MOD music.
(Edit, huh, .ZOO was based on LSW, so maybe I'm conflating the two)
LZW sounds familiar, LZJ doesn't.
powerpacker or bust, baby
Oh wow, ARJ, and of course, ARC. Now I want to dial up to a BBS with my fancy 14.4K modem and download WADs via ZMODEM.
.ace and WinAce -- which died out fast, and eventually had a nasty security bug in unacev2.dll that caused it to be removed from most 3rd party utilities.
