    7-Zip 16.02 was released.

    7-Zip for 32-bit Windows:


    7-Zip for 64-bit Windows x64:


    What's new after 7-Zip 16.01:

    • The BUG in 16.00 - 16.01 was fixed:
      7-Zip mistakenly reported the warning
      "There are some data after the end of the payload data"
      for split archives.

      MSI Installer 16.02:
      On WinXPx32 and Win7x64 - writes file associations OK
      On Win7x32 - doesn't.

        Installer doesn't write file associations.
        You can to set file associations in 7-Zip/Tools/Options after installation.

        • Alexander Davidenko

          Thank you!
          Is it possible to make file associations during installation? I.e. msi commandline switch?

          An option to associate during setup would be a very nice feature. :)
          Windows 10 requires an additional step (Opening the program as an administrator) to associate file types making it that much more of a nuisance.
          Thank You, as always, for your work!

      Hello, we noticed that a very large amount of machines have explorer.exe fail to restart on its own after the latest 7-zip gets installed. It always succeed to close explorer.exe, install 7-zip fine but often fail to restart explorer.exe. We have seen that on both Win7 x86 (French OS) and Win7 x64 (French OS). Eventviewer error says: fail to restart exlorer.exe application sid does not match conductor sid. Any thoughts ?

      languages textfiles:

      why do you not easy the whole textfiles in a 7z-lang.7z instead of a folder ?
      with this it is possible for clean integrating in, as example reactos or an other windows
      in system-folder.

      with 7z it is possible for readout on the fly 7z compressed archives, so, why then not on the fly
      let read out the lg.txt in a //lang-7z.7z/de.txt or //lang-7z.7z/ru.txt and so on.
      with this it is possible for have the whole langfiles in one compression file
      and can read out as a "compression folder"

      By the way, can you create a inf-file and by side a regfile for integrating in windowsNT as compression file reader as folders ? In windows , with this possible would it also possible for
      take the package to make a installer with other libarys together and integrate your z7 fully in the Explorer as example in Reactos or an other WinNT by add the regestry-strings in the installer ;) .

      best regards

        There are some reasons.
        For example, 7-zip.dll (context menu dll) reads language file.
        If we need to unpack txt file from 7z archive, we also must load big 7z.dll for that task. So 7-zip.dll loading will be more slow.

      Hello Igor,
      In this version 7z.exe make volumes by 2Gb archive over network connected drive -> 1 % is bad.. (-mmt=1, -w drive is eqial to arch file path). But some of them broken.. And I'm need make additional test after creation -> for example Corel Suite x86&x84. So archive makes broken (, more stable using 7zip GUI.

      Hello Igor,
      Please add new "-vrst" key -> Reset volume stat's and create independent solid volumes.

      By default 7-Zip tries to reset solid statistics as soon as possible when starting a new volume, but only if enough data was packed after a previous reset (at least a few megabytes).

      This switch forces 7-Zip to ignore stat's in packed data size and attempt to reset statistics for volumes of any size. It decreases compression, but increases chances to extract a part of data if one of several solid volumes in a volume set was lost or damaged.

      And thank you to "writeback" function -> take care for previous first volumes.

    That was fast, great work Igor. As soon as you were able to wade through my novice archive lingo, you found the problem and fixed it. Thanks again.

    Your quick attention to issues is appreciated.

    Should I be concerned that the x64 Edition installs into Program Files (x86)?

    Great product.

    Is it possible to have an option to Compare and Save the calculated checksum (CRC32 ; CRC64 ; SHA256 ; SHA1 ; BLAKE2sp) through the 7-Zip GUI? At the moment I can only see it.

        Great. I guess I missed the shortcut option.

        NOTE: I found a website (http://text-compare.com/) where to compare the strings.

  • Andrew McGlashan

    Under "Files", the latest right now is 16.01, at least that is what I see. Also, if people go to "Files" and then "7-zip", there is an "i" icon to the right for more information, you get checksums there.

    I too would like to see digital signing of the files with GPG and/or internally as well with a proper certificate.

    Great work.

    I noted that the command line version reports itself as, shouldn't that be instead?

      No, it is correct, just the leading zero is skipped. The following zeroes are for further versioning, probably not needed at the moment. So 16.02 = 16.2 = =

      @Igor: Thanks for Your great work

    Hi Igor I can no longer open new tickets here, so I here's the Chinese Simplified language update for the new version with some misleading translation fixed.

    • Igor Pavlov

      Igor Pavlov - 2016-05-23

      Yes, if I set "moderation" mode, it's impossible to create new tickets at sourceforge. It's flaw of sourceforge system as I suppose.
      But you still can add new posts to old tickets.

    Is there any network access action in 7zFM.exe?

    My firewall always notify me that 7zFM.exe try to access internet, one of the target address is, what is happenning?

    Can you post a checksum of install packages on download page?

    • Igor Pavlov

      Igor Pavlov - 2016-05-23

      1) 7-Zip doesn't acess internet.

      2) You can find sha1 for package at:
      Then you can download exe package and compare CRC32 or SHA256 for any file inside package and the copy at your system.

        I was asking myself the same question made by qaqz111.

        In consideration of this kind of "possible" accidents, though, isn't it a little bit too risky to avoid supplying an OFFICIAL CHECKSUM resume on the homepage of 7-zip, and - what's even more important - a digital signature of yours, against which one can control s/he has actually downloaded the legit 7-zip application, and not a fake? (Yes, I know that the case analyzed by ReaQTa is quite another story... but, anyway... )

        By the way: were you already aware of that case?
