    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?

    Reviewing 9.38 Beta (Apr 4, 2015)

    7-Zip still doesn't support file recovery redundancy data to protect archive files against file damage, nor does 7-Zip support a larger file checksum than 32-bit CRC32.

    WinRAR has options for file recovery and 256-bit BLAKE2 file hash.

    7z isn't as robust for long-term storage as the better RAR file format.

    Free is NOT always better!!

    Way better than WinRAR, and completely free. I use this every single day.
