    Why not use gcc - virtualbox uses GCC for 32 and 64 bit, and I should think it has more code than 7zip. They seem to think it isn't buggy.

    Is it a performance issue?

      The code from GCC was not fast for x86 in past.
      Maybe now GCC is good enough for performance.
      But I'll try VS 2013.
      And if there is some problem, I'll think about something else.

        If you use VS 2013 be sure to make it compatible with Windows XP and older CPUs. By default VS 2013 requires Windows Vista or later and a CPU supporting SSE2 or later.

        Here is the way to get it to work with older CPUs: http://msdn.microsoft.com/en-us/library/7t5yh4fd.aspx - use the "/arch:IA32" option in VS 2013.

        To get it to work with Windows XP in VS 2013, go to project, properties, general, and set the Platform Toolset to "v120_xp".

        Lately I've noticed a lot of programs compiled in VS 2012 or 2013 not working on older CPUs that don't have SSE2, thanks to the default in both those versions being "/arch:SSE2". My own computer has a CPU that doesn't support SSE2 (AMD Sempron 2800+). So please be careful to maximize compatibility if you use the newer MS Visual Studio versions.

        One of the advantages of GCC is its default options don't cause any compatibility problems, and work with a wider variety of CPUs and versions of Windows (as well as dozens of other operating systems too)... but yes, MS Visual Studio's compiler does tend to produce executables that are smaller in size and a bit faster, although mostly the difference in speed is because of different default optimization settings in GCC and MS Visual Studio (GCC is set to work with anything back to a 386 by default while MS Visual Studio is set to require at least an Intel Pentium 4 or AMD Athlon 64 by default, and while recent versions of MS Visual Studio can only support Windows XP and later, GCC still supports everything back to Windows 98).

      Did you test that translation file in 7-Zip and does it work?

      Write more information about language and script.
      What Unicode range is used (why Unicode codes like E5EB)?
      Does it require to install font?
      How many users have that font installed now?

    Users are not too much, has tens of thousands of!!!! Use our Unicode beginning, Windows 7, doing system support, but the desktop text is too small, does not support WINXP (already installed support library), I've just sent to you we are using here,
    I can't speak English, I use translation software translation!!

      Is it Mongolian script?
      http://en.wikipedia.org/wiki/Mongolian_script
      The Unicode block for Mongolian is U+1800–U+18AF.

      But why your file uses another Unicode codes?
      I can't see these characters in Windows 7.

    How are you? Do you have instant messaging software? Such as Windows Live Messenge, my ID is saqirilatu@126.com

      We don't need messaging software.
      This forum is better.
      You can create new thread in Tickets/Patches section and upload translation file there (with only one txt file in archive).
      And please answer my questions in that new thread:

      Is it Mongolian script?
      http://en.wikipedia.org/wiki/Mongolian_script
      The Unicode block for Mongolian is U+1800–U+18AF.
      So why your file uses another Unicode codes?

    Windows 7 and doing the Mongolian Unicode inside there is a problem, this is not a Unicode, another kind of coding, Menksoft coding (www.menksoft.com)

    In 9.32 I can not open archives in archives.
    Eg open zip with files plus another zip inside, attempting to open the zip inside "inside" or "outside" gives error message that the archive could not be opened.

    This happens in all files cases I can find. The same files open fine in 9.30.

    Example file, 9.32 can not open firmware.zip while 9.30 can:
    http://fotadl.htc.com/OTA_EVITA_UL_JB_50_S_Orange_UK_5.14.61.2-3.17.61.1_release_341164uhscsguuxog0wwex.zip

    My machine:
    Windows 8.1 x64
    7zip 9.32 32 and 64bit suffered from the same issue.

    However I did find a few zip files 9.30 could not extract files from(but did list contents fine) that now work correctly in 9.32 :)

      7-zip can open zip in zip.
      But there is problem with htc zip archive.
      It contains file firmware.zip
      But firmware.zip is not good ZIP archive.
      firmware.zip consists of some 256 bytes at start and then ZIP archive.
      New 7-Zip doesn't want to open such ZIP.
      But you can open it via menu Open -> ZIP or Open -> #.
      Also you can open it, if you change extension of file: firmware.ttt.

      Why 7-Zip doesn't want to open 256 bytes + zip as zip archive.
      Imagine such situation:
      You have 1 KB small.zip and 10 GB of another data in many files.
      You archive all of these files to big.zip.
      Then big.zip was corrupted by some reason.
      And you call "Test archive" operation.
      7-Zip can't open big.zip, but it can open small.zip inside big.zip.
      It can show that it's OK with small.zip, but user wants to open and test big.zip.
      So it's more safe to say that it can't open most expected archive - big.zip.

        256bytes is HTC signature.
        Android having signature for zip's is common although I believe APK has signature at the end of the file instead of the start.
        Infact OTA_EVITA_UL_JB_50_S_Orange_UK_5.14.61.2-3.17.61.1_release_341164uhscsguuxog0wwex.zip is signed at the end of the file.

        I know 7-zip has never supported writing to these zip files because of the signature at the beginning but always supported reading.
        It would be at least nice to have an option to continue opening these archives like older 7-zip could.

        eg a checkbox for "ignore nonstandard data before archive"

        Perhaps this option would even let the user write to the zip with the 256bytes at the start untouched, creating a zip with a non-matching signature.

        Edit: From what I am reading, signatures at the start or the end of the file is not outside of zip specifications.

        Want "Open inside as" menu.

         
  • Thanks for the new alpha Igor, but could you please consider adding an option to verify a password when an archive is being created? At the moment a typo when typing the password can easily render the archive useless.

    Hi I compressed an EXE file with v9.22 and v9.32 but v9.22 gave a bit smaller size than v9.32 then I added f=bcj for v9.32 and file size became smaller than v9.22.
