Stuffit Expander 4 was the most popular archives decompression utility for Mac back in the early 90's. It supports many compression formats such as .sit, .bin, .hqx and .zip. Stuffit Expander 4 was superseded by Stuffit Expander 5 in the mid 90's. Since Stuffit Expander 5.5 requires Mac OS 7.5 or later, Stuffit Expander 4 remains the best option for Mac OS 7.0 and 7.1 environments.
