Zoo is a compressed archive format developed by Rahul Dhesi. It was one of the many competing archive formats in the 1980s, and was based (originally) on LZW compression. It had some popularity with Open/VMS and Amiga systems, but didn't ultimately win out over ZIP.

Contents

Discussion

The Zoo software encompassed several different utilities, which were sometimes distributed individually, and which had their own version numbers.

  • Zoo - The main program
  • Ooz - Extractor
  • Booz (Barebones Ooz) - Extractor; some versions can also list files
  • Looz (Ooz with List) - Extract/list/execute
  • Atoz - Helper utility for converting other formats (ARC, LBR) to Zoo
  • Fiz - Analyze damaged Zoo files
  • Stuff - File finder

Identification

Files have bytes DC A7 C4 FD at offset 20.

Compression

There are three known compression methods:

  • 0 - uncompressed
  • 1 - LZW, also called "LZD"
  • 2 - LZH
