Panther Unzip 1.0 Description:
Panther Unzip is a little utility I wrote to decompress Panther style zip archives under other versions of Mac OS X and keep the resource forks and creator/type codes in tact.
I haven't found a machine running Mac OS X v10.1 to try out this program. There's no reason it shouldn't work and I've confirmed that 10.2 works. It works under 10.3 but that would just be silly.
