    7-Zip 9.33 alpha was released.

    This is a development version.
    Don't use this alpha version to process important files and archives.
    The code of this version contains big number of changes.
    And probably there are some new BUGs.
    If you use 7-Zip 9.33 alpha, check 7-Zip's forum periodically for updated information.

    If you need more stable version, you can use previous versions: 7-Zip 9.25 alpha or 7-Zip 9.30 alpha.

    7-Zip for 32-bit Windows:


    7-Zip for 64-bit Windows x64:


    7-Zip 9.32 alpha version is provided without source code.
    Source code will be released in future beta version.

    Please write here at forum about any new bugs.

    What's new after 7-Zip 9.32 alpha:

    • 7-Zip now can show icons for 7-Zip items in Explorer's context menu.
    • "Add to archive" dialog box:
      • new options in "Path Mode"
      • new option "Delete files after compression"
      • new "NTFS" options for WIM and TAR formats:
      • Store symbolic links
      • Store hard links
      • Store alternate data streams
      • Store file security
    • "Extract" dialog box:
      • new optional field to set output folder name
      • new option "Eliminate duplication of root folder"
      • new option "Absolute pathnames" in "Path Mode".
      • new option "Restore file security" (that works for WIM archives only)
    • 7-Zip File Manager:
      • new "File / Link" dialog box in to create symbolic links and hard links.
    • Command line version:
      • new -spd switch to Disable wildcard matching for file names
      • new -spe switch to Eliminate duplication of root folder for extract archive command
      • new -snh switch to store hard links as links (WIM and TAR formats only)
      • new -snl switch to store symbolic links as links (WIM and TAR formats only)
    • NSIS support was improved.
    • The problem was fixed:
      The command "extract to *" with multiple archives could use same
      output folder, if archives are placed inside PE (EXE) file.
    • The BUG of 9.31-9.32 was fixed:
      Command line version for test and extract commands returned the
      value 0 as exit code, if it couldn't open archive.
    • The BUG was fixed:
      7-Zip could not create archives with anti-items for any archive type,
      except of 7z type
    • Some bugs were fixed.
    • New localization: Mongolian (script).

      still no support
      I'm disappointed. You could have saved us from using WinRAR, now I have to wait another 7 months until it will probably be supported.

        Also, ISO issues haven't been fixed.

        Maybe in a few years..

      Hi, Igor.

      Thank you very much to fix this bug. http://sourceforge.net/p/sevenzip/discussion/45797/thread/49e6a4d4/?limit=25&page=1#0a59

      The BUG of 9.31-9.32 was fixed:
      Command line version for test and extract commands returned the
      value 0 as exit code, if it couldn't open archive.

      I was able to confirm the fix in my environment.
      Thank you for new release!

      Thanks a lot Igor for releasing the SHA-1 sums for all versions, that is important for end users. Please do the same with every new release on future. Your programs is excellent and extremelly useful for all of us.

    Hi, Igor.
    Thanks for a new, long-awaited version.
    Thanks for the icons in the context menu, but why is there a non-standard 7-Zip icon? A new, smaller icon looks ugly. :( Is it possible to replace the standard?

    Thanks, Igor.
    Would like to request a password manager/keeper. I think I saw the request for one a few years back and the response was that it was not a good idea to keep you pass for everyone to find it. While I do think it is stupid to store passwords in a computer that you share, most of us don't. The main reason this option would be nice is cloud storage is growing more, and more every day. And (I) everyone is probably compressing the files with a password.

      I'd think it'd be better to use a dedicated password manager for this?

      It's a lot of functionality, and I can't see how one could easily integrate it well into an application like 7-Zip anyway...

      • Byron Taz

        I have a password manager, but it wont work with 7-zip. WinRAR has had a password keeper for years, but 7-Zip is my go to archiver (better compression). And at the end of the day its all about size.

        • ZiNgA BuRgA

          ZiNgA BuRgA - 2014-06-18

          I don't have WinRAR, so don't know what it's like, but have you tried PeaZip (supports 7z and has a password manager) before?

          • Byron Taz

            Byron Taz - 2014-06-18

            Thanks ZiNgA BuRgA, but I don't want a 3rd archiver. I might not have WinRAR installed now if 7-Zip could process RAR5.

            Thanks anyway.

    Hi Igor,
    Thx for the new Dev Build ;^_^

    • Why not make x86 and x64 editions in one package?
    • Why not make the hash text in dialog of CRC SHA can copied, I know the dialog can copied like this:


    name: XX.exe
    size: 860488 bytes (0 MB)

    SHA256: 74C8B614672D1A7F0889243056EA4B3E03B5F66DFDFEFF5DD6CC17DBE088D18F


    • ZiNgA BuRgA

      ZiNgA BuRgA - 2014-06-18

      You mean like this?

      Checksum information
      Files: 1
      Folders: 0
      Size: 3 bytes
      CRC checksum for data: 352441C2
      CRC checksum for data and names: A6F2C207
      SHA-256: BA7816BF8F01CFEA414140DE5DAE2223B00361A396177A9CB410FF61F20015AD

      You can just press Ctrl+C when the dialog is open to copy the text.

        If add in the dialog button "COPY", it will be more convenient.

          I believe it's just a standard Windows MessageBox, which doesn't give the programmer the ability to provide such functionality. You'd probably have to ask Microsoft to add that functionality, unfortunately.

    About menu icon size.
    Now it's 13x13 icon.
    As I remember there were some reasons to use that size. Maybe it was for compatibility with WinXP system.

    I didn't look that problem deeply.
    So if someone can tell more about sizes and different Windows versions, please write here.

    About NSIS.

    7-Zip 9.33 alpha now shows decompiled script file "[NSIS].nsi" in NSIS installers. But the code for script decompiling is pretty bloated and useless for most users. So maybe that feature will be disabled in final release of 7-Zip. I can switch it on/off at compile time.

    So if nsi script decompiling is interesting for someone, please write here your comments and notes.

      Imo, it is a very nice addition, it remember what innounp does for Inno, but it seems to be more powerful for NSIS.
      "the code for script decompiling is pretty bloated", but does it cause visible performance impact?

      9.33 looks promising for a beta or final release (time for v14.00?)
      - CRC item in context menu is placed outside of "7-Zip" when "Cascaded context menu" is enabled.
      - Is it intended to show extraction's options in context menu for files with ".log" extension? (maybe other extensions too)

        There is no big difference in performance for most NSIS installers. But decompile code is big, so executable is larger (maybe 30KB-40KB larger).

        • "CRC" menu item outside of 7-zip. I wanted to show that CRC calculation feature is not related to main 7-Zip tasks (compressing and decompressing).
        • "log" extension. I have special list of "exclude extracting" extensions. I'll add "log" extension in next version.
        • Sr. Zé Alguém

          Sr. Zé Alguém - 2014-06-17

          Add .mht, .eml, .mbs too, unless you plan to parse these and extract attachments.

      now shows decompiled script file "[NSIS].nsi" in NSIS installers.
      This is a wonderful addition, it is necessary to leave.

      •new optional field to set output folder name
      Help is not a word about it.

        Opened NSIS file IE7ProSetup_2.5.1.exe.
        It saw the file 'uninst.exe.nsis'.
        What is this file?
