QFC is a program designed to reduce the size of archives. It is similar to the UNIX program tar. Instead of compressing individual files like Zip does, QFC combines files into one big file, which can be compressed more effectively.
It was written by George Lyapko; the original 2.02c version can be found here.
QFC v3.02 (37k, includes Pascal/assembly source).
