- The FAQ (Frequently Asked Questions) for the groups comp.compression
- and comp.compression.research is posted in comp.compression only.
- This article is just a reminder, posted more frequently.
- *Please* read the complete FAQ before posting in either group.

- For a decompressor for a file with extension .arc, .lzh, .zip, .zoo,
- .Z, etc..., see item 2. For graphics formats, see item 54. For CCITT
- standards, see items 11, 18 or 20.
