Open Source File Compression Software

For years I was an advocate of PKZip and WinZip (That I own a “floppy” disk of), but after discovering the advantages and freedom of open-source, I discovered 7Zip.

7-Zip is a file archiver with the high compression ratio. The program supports 7z, ZIP, CAB, RAR, ARJ, LZH, CHM, GZIP, BZIP2, Z, TAR, CPIO, RPM and DEB formats.

While it’s only available on Windows, similar software is native on most other Operating Systems, Microsoft added only meager support in Windows XP (which in fact often crashes machines).
