Released 1985

ZSQ is a file compression utility developed by Wayne Chin and Arvind Kumar. It describes itself as "File Squeezer using LZW compression algorithm". The companion decompression utility is ZUSQ.

ZSQ might have been a contestant in the race to make a usable format based on LZWCOM, but lost to ARC and Crunch. It uses the same file naming pattern as Crunch.

Identification

Files apparently start with ASCII "WACK".
