    Igor Pavlov - 2011-03-27

    7-Zip 9.20.09 alpha was released.

    7-Zip for 32-bit Windows:

    http://dl.7-zip.org/7z920.09.exe
    or
    http://dl.7-zip.org/7z920.09.msi

    7-Zip for 64-bit Windows x64:

    http://dl.7-zip.org/7z920.09-x64.msi

    What's new:

    - 7-Zip now can unpack UEFI BIOS files.
    - 64-bit version of 7-Zip now includes additional 32-bit shell extension DLL.
      So other 32-bit programs can call 64-bit 7-Zip via context menu.
    - Now it's possible to associate 7-Zip with file types without Administrator rights.
    - New -mf=FilterID switch to specify compression filter. Examples:
        7z a -mf=bcj2 a.7z a.tar
        7z a -mf=delta:4 a.7z a.wav
        7z a -mf=bcj a.tar.xz a.tar
    - There are some changes in LZMA settings for BCJ2 filter.
      So compression ratio now is slightly improved for executable files in -mx9 mode for .7z format.
    - Some bugs were fixed.
    - New localizations: Corsican, Kyrgyz, Ligurian.

    What's new in latest alpha update:
    - The bug was fixed: 7-Zip File Manager could work incorrectly with archives in "Flat View" mode.
    - 7-Zip File Manager now can update file in archive even if the file name is not supported by Windows.

    If you see some new bugs, please write here.

    1 In opened password protected 7z archive, open/copy/extract operations works fine,  while testing ask for password once again.
    2 Broken rar archive handling, causing File Manager crash still present.

    1. What File Manager do you mean?

    Do you have problems with command line version:
    7z l bad.rar
    ?

    Do you have problems with any truncated rar file?

    It works OK in 64-bit XP.
    Please describe exact key strokes to reproduce the problem.
    Check also that you have only one version of 7-Zip in your computer.

    1. Check that you have only one version of 7-zip and that is latest version.
    2. Check that 7zfm.exe and 7z.dll have timestamps of Mar-2011.
    3. call 7zfm.exe from command line:
    7zfm.exe err.rar
    7zg.exe t err.rar

    Why isn't this patch http://sourceforge.net/projects/sevenzip/forums/forum/45797/topic/3564462 (option for open output folder after extraction) or an official replacement in this new build ?
    Will this option be implemented ?
