Free File Archivers and File Compression Utilities - Compress / Decompress (Uncompress) / Archive Files
This page lists free tools that will allow you to compress, decompress (uncompress), and archive files. Most of the utilities listed here handle the ubiquitous zip file format, and many (if not all of the software listed) can decompress files using a variety of file compression formats.

- FreeArc Archiver
[Update (6 March 2017): the domain that previously had the FreeArc software appears to have expired. For the record, the site used to be at
freearc.org.] FreeArc is a general purpose archiver (which means it handles all sorts of files and is not a specialized compression program like an audio compression utility, etc), that boasts of fast compression times, recovery of corrupted archive files, the ability to create self extracting executable archives (SFX) and installers, the ability to create encrypted archives, etc. It is also able to directly list and extract files from the internet (that is, it will download the file for you and allow you to list it or extract its contents). As far as I can tell, FreeArc uses its own file format (that is, not zip or the like). The program is free and is released under an open source licence.
