A Macintosh archival compression program, similar to StuffIt but using
its own compression algorithm (.cpt). Originally called "Compactor",
it could also create self-extracting archives (.sea), expand early
StuffIt files, and read/write .hqx and .bin files for distributing
over networks. Compact Pro for several years in the early 1990's was a
serious and popular competitor to StuffIt. It was the first shareware
program to win a MacUser "Eddy" (Editors' Choice) award. However since
2003 it has been discontinued and is unsupported.
