    I'm having trouble extracting the CAB files I get from Microsoft Windows Server Update Services. If I extract them with 7z, I get basically the same result as extracting them with Microsofts "expand" command, but the most important parts are missing, while MS "expand" expands this correctly and completely. The parts that seem to be incomplete with 7z are in subdirs when MS "expand" is used.
    Example-File:
    B8CEC590CCF1EBC057969C1C760BA290E38FC801.cab

    You might say why don't I just use expand then instead? Well, the reason is, I need to extract the files under Unix. However this problem is reproducible on Windows and Unix.

    I need the link to such CAB file to test it.

    And check 7-Zip 9.22 beta also.

    I don't see any difference.
    maybe my exapnd is old.
    Show what the difference do you see.
    what exact sizes and names of addiitional files.

    Check also that you use latest 7-Zip 9.20.

    I didn't know about that new feature of CAB.
    I'll check it later. Thanks!

    Any news on this one? Do you plan to implement IPD compatible extraction?

    That IPD feature is not so simple to implement.
    Now I don't want to spend time for that feature.
    Maybe later I'll try.

    Still no plans to support the extracting of CAB files?
