ZOO was one of the many competing archive formats in the 1980s, and was based on the LZW compression system. It had some popularity with Open/VMS and Amiga systems, but didn't ultimately win out over ZIP.
Contents |
Identification
Files have bytes DC A7 C4 FD at offset 20.
Compression
There are three known compression algorithms: 0 is uncompressed; 1 is LZW, also called "LZD"; 2 is "LZH".
Software
- Konvertor
- zoo-2.10pl1.tar.gz
- zoo-2.10-3.src.rpm
- unzoo.c (Does not support LZW/LZD.)
Sample files
