7zX is a file archiver with high compression ratio. Compression ratio results are very dependent upon the data used for the tests.
Usually 7zX compresses to 7z format 30-70% better than to zip format, and 2-10% better than most of other zip compatible programs.
7zX currently supports tar, zip, gzip, bzip2, UNIX compress, 7z, s7z and various kinds of segmented archives.
It supports Mac resource forks and Spotlight metadata, and can also create Self-Extracting archives.
- The bug that caused 7zX to produce bus errors on certain machines should be now fixed.
- Software Update should work correctly once again.
- Mac OS X 10.4 or later (OS X 10.3.9 could also work).
