7-Zip 9.31 Alpha

Recommended Posts

7-Zip is an open-source file archiver, that offers the highest compression ratio, using the new 7z format, which delivers compression results that are usually 30-50% better than standard ZIP. We tested it with a server log file, which compressed with ZIP had a file size of 18 mb and using 7-Zip was reduced to 8 Mb (results may vary, depending on file type). 7Zip supports 7z, ZIP, CAB, RAR, ARJ, GZIP, BZIP2, TAR, CPIO, RPM and DEB formats, so it can be used with all popular archive files. The program offers a basic file explorer interface and also integrates into the Windows right-click menu. It can be associated with any of the supported formats and also offers command/line support.

Thanks to jasonliul for the update.

Gr8 2 finally c a new release but it's sad that the development have been going forward so slow and no RAR5 support added...... that's really bad.

:lol: I wonder why you guys so concerned about RAR5 support. IMO top priority now is fixing every possible bugs exist and add more feature/capability on 7z format itself :)

I'm glad to see they are still working on their software. Been using it for years.
