Archive Converter bug - 7-ZIP



  • When converting to 7-ZIP ultra, the memory usage is around 200 MB - that’s not ultra, it’s more like maximum!



  • Anybody??

    When converting to 7-ZIP ultra, the memory usage is around 200 MB - that’s not ultra, it’s more like maximum!

    Didn’t realise this was question :p

    Converting from ??
    Size of data (uncompressed) ?
    How are you measuring the memory usage ?
    If you compress the data with 7z(ultra) is the resulting archive different to the converted file?

    Edit: If you compress the data with 7z(maximum) is the resulting archive different to the converted file?



  • The archive type to convert from is irrelevant - PA extracts to temp first.
    Size of data was about 500 MB, even tried 2GB.
    Task Manager shows the memory usage.
    Didn’t try manual compression for comparison.

    The point is that Ultra uses 700 MB of memory for compression, not 200!! 200 is what maximum uses!
    The compression takes long enough, so that the memory usage should reach its peak of 700.

    Any thoughts?

    try doing 2 conversions - one with maximum and one with ultra settings and see if they are the same size wise…
