    OPEN SOURCE, compared to copyright (foreign, unknown) stuff hidden in newish RAR, etc.
    Also available as 32 bit.
    Allows compression, decompression of many file types.
    Regularly improved, upgraded, with compatibility with many older & freeware versions.
    State of the art GUI menu interface, with good folder usage, file usage.
    Version inbuilt into my favorite file browser (Servant Salamander) is faster, & almost as tightly compressed.
    7-zip is used as a benchmark standard by many reviewing sites.
    Benchmarking allows 8-core tests.
    Ultra-compilation only allows 2-core, with very small improvement on overall compression.

    Its very good but not IMO as good as Winrar, but I don't think anything is - Great for free though!

    The only program to use, forget winzip and there charges this is free and does the same job if not better.

    dhry, refer here for Igor Pavlov's own explanation as to what seems like 7-Zip's odd version numbering: http://sourceforge.net/p...n/45797/thread/e127e39c . This is an old explanation but still holds true.

    Why the did version of this program go from 9.38 to 15.00?
