Original UltraCompressor II

Nico de Vries created UltraCompressor II (1992--1996), a DOS archiver with LZ77+Huffman compression, master-block deduplication, and file versioning. The original source code is preserved in original/UC2_source/.

Source Code Release

Danny Bezemer facilitated the public release of the UC2 source code in 2015 under the LGPL-3.0 license.

Portable Decompressor (unuc2 / libunuc2)

Jan Bobrowski wrote a clean-room portable decompressor (2020--2021) that forms the foundation of this project's decompression engine. The library (libunuc2) is licensed under LGPL-3.0; the CLI tool (unuc2) is licensed under GPL-3.0.
