    If I work for RAR5 code, I don't change main code of 7-Zip. So rar5 will not delay the release.

      @Igor I thing what szfong meant is labeling your "Betas" as "stable releases".
      I humbly agree with szfong. The community is long time waiting for a 7zip "stable release"; something that i.e. a manager somewhere (that does not read this forum) can take as a clear indication that this project is actively being developed and not abandoned at all.

    Hi Igor,

    If it's not too much trouble, adding a:

    WinRAR equivalent of
    -ds Do not sort files while adding to a solid archive.

    would be great as I've notice MUCH higher compression when compressing files with many sub-directories or multilevel sub-directories....

    Hello Igor,
    Thank you for best archiver ;)

    Sorry but versions 7-Zip 9.34 and 9.33 can't add busy/shared files (see attachment), 1C Bases in this example

    7-Zip 9.32 can do this.

    This is bug i'm checked from GUI, but in command string also possible contain this error...

    Best regards,

    Oleg

    p.s: compress shared files checked in all exaples.

    Bug report on Ru.Board

    In the console versions 9.33a and 9.34a archiver something is not working the switch -spf.
    For example, if you execute the following command does not find archive files to compress:
    7z.exe a -r -spf archive.7z \\Server\Work\*.doc
    In 9.30a still worked ...

    Hi Igor,
    thank you for adding the options for hard and symbolic links.

    This version seems to store and extract hard links properly, but it has problems with symlinks.
    When I create a tar file containing symlinks, 7-zip file manager doesn't even show the file name in the symlink column, and fails to extract the symlinks correctly.

    Also, when I open a tar file with symlinks (created using tar), 7-zip file manager shows the symlink name correctly in the symlink columnn, but fails to extract the symlink correctly.

      1) what is your WINDOWS version?
      2) you must run 7-Zip File Manager with administrator rights.

      If you still have problems, please follow the following steps:
      1) run 7-Zip File Manager with administrator rights
      2) create file.txt
      3) create symlink.txt to file.txt (via 7-Zip File Manager)
      7-zip File Manager must show the link in Link column.
      4) select both .txt files and create a.tar with "store symbolic links" enabled.
      5) open a.tar

        Thanks Igor! I did not run 7-zip with administrator rights. After I did, this worked fine. Thanks!

    Hello Igor,
    we made an update of 7-zip from 9.25 to 9.32 for our Win7-x64 systems. Now, after rollout, i got this error:

    ZIP Files created on z/OS Host System with „Zip 2.2 (November 3rd 1997)“ can now not be opened with 7-zip versions 9.32 or 9.34 (x64) on Windows systems. Error „Can not open file xyz.zip as archive" is displayed
    With 7-zip version 9.25 everything was ok.

    (Please see Attachments here; also a test.zip for you)

    But ZIP-Files created on (newer) Linux System with newer version of Info-ZIP „3.0 (July 5th 2008)“ can still be opened with 7-zip 9.25/9.32/9.34 !!

      There is error in Extra Field of local-header.
      7-Zip doesn't like such errors in header of first file in zip. It checks it to ensure that it's real zip file.

      Proably it's known bug of old ZIP 2.2. But now I can't find any references to that bug.

      Maybe I'll change the code to work with such files.

      WinZip now supports xz compression as "95" method.
      I have working xz code.
      So I can add decoding for "95" to 7-Zip too.

       
      • paf22

        paf22 - 2014-06-26

        Coooool!
        Then please, add it for the next version.
        Thank you very much in advance! =D

        Subsidiary question: Why not add automatically all compression/decompression code you have working? To keep 7zip as small as possible?

         
        • Igor Pavlov

          Igor Pavlov - 2014-06-26

          xz in WinZip (zipx) is pretty new feature. Now when I have example of such archive, I can add that feature to 7-Zip (unpacking only).

          xz code is already included in 7z.dll. So zip code will just call that xz code. Maybe it's additional 1 KB. So 7zip's size is not problem here.

          I will not add xz-zipx encoding in near versions. It's more difficult to implement and test compatibility of encoding code than decoding code.

    paf22 - 2014-06-26

    Ok, nice.
    Thank you in advance for adding this decoding-code in next version.
    No problem for not implementing xz-zipx encoding code since LZMA2-ultra-7zip seems equal or better in most of case for me. :)

    Hello Igor,

    Folder entries are now(?) stored before other entries (e.g. files), at least by 7za.
    Thus, folder timestamps are no longer properly restored.
    Is this an intended behaviour? (sorry if this has already been asked formerly)

     
    • Igor Pavlov

      Igor Pavlov - 2014-06-28

      Did you check it?
      7-Zip makes second pass for folders. So it must restore timestamps.

       
  • Anonymous - 2014-06-28

    Oops... I built the test archive with 9.34, but inadvertently extracted it with a former version, sorry.
    Thanks for your reply Igor.

    The manual describes two ways to call Extract Dialog Box, but it's different dialogues! Or am I mistaken?

    extract

    copyto

     
    • Igor Pavlov

      Igor Pavlov - 2014-06-29

      Probably I used "Extract" dialog in past for open archive, but then there were reasons to use "Copy" dialog instead.
      I'll fix the help.
