StuffIt 3.0 fought back with an even more powerful compression algorithm, a shareware version called StuffIt Lite with most of the same features, and the freeware StuffIt Expander which could decompress StuffIt archives and Compact Pro archives. Compact Pro never really regained its momentum after the release of StuffIt Expander. It maintained a niche among loyal users and as a preparation tool for Cyclos's "Smaller Installer" delivery package (which was notably used by Ambrosia Software), but disappeared from the market by the late 1990s.
