    Hi,
    I want (and actually have to) cerate a ZIP file using PPMd. This should be possible according to the manual of -m switch. However, that's what I receive:

    $ 7z a -tzip -m0=ppmd test2.zipx test1.py
    7-Zip [64] 9.20  Copyright (c) 1999-2010 Igor Pavlov  2010-11-18
    p7zip Version 9.20 (locale=en_US.utf8,Utf16=on,HugeFiles=on,2 CPUs)
    Scanning
    Creating archive test2.zipx
    System error:
    E_INVALIDARG
    

    Any ideas or tips? I can't use other software or other format.
