Softlib

Softlib was a compression/archiving program used by Softdisk Publishing in the 1990s as a container format for their programs and data, but not actually released directly as a published program. Some game data files used in the Gamer's Edge product were compressed this way (with the decompression algorithm built into the game program itself), and various self-extracting installers for Softdisk products used the Softlib format for their compressed data.
