What's a medium requset, is that like a long-tailed marmoset?

Directory Opus and the PD program Ordering, both of which are
excellent and essential Amiga file managers have inbuilt LHA
decompression buttons.
Just put LHA into Workbench:C/ and you'll be fine. The latest version
of LHA is best as it fixes Y2K problems.
They do say though that LZX has far better compression ratios. Plenty
of GUI-based tools on Aminet for decompressing/compressing... you just
need the little files that go in C: like LHA,LZX,DMS,ZIP,RAR,unTGZ
etc.
