Unzip operation hangs



  • Method is Bzip2, compression is normal. The file was split using Winzip (I don’t see a split/span mode type option in Winzip).


  • conexware

    what version of PA are you using exactly?



  • 11.60.20


  • conexware

    and do you know what version of WinZip? And what settings did you use? So we can try to re-create the archive.

    thanks



  • The flow is rather strange. The archive was originally created with 7zip using Method=Bzip2, compression=normal. The archive was one large file.

    After the archive was created it was transferred across a wan where it was decided it should be split. The user only had Winzip 11.2 (build 8094) and split the file into DVD sized files.

    I can unzip the split archive on my local machine using 7zip, Winzip, and Winrar. The only problem is with the latest build of PA.

    hm, i have to find some older WZ because latest versions report an error when splitting large zip created with 7zip.

  • Is the new 11.60 build release today supposed to address this? If so, it still hangs. If not, never mind :).

    nope, could not reproduce.

    are these vmware image files downloadable somewhere? i have tried creating similar example, but everything worked fine. It might be something that was special to files compressed.



  • No, the image files are not distributable. I will see if I can come up with a reproducible scenario and set of accompanying steps.

    that would definetly help us solve the issue…. i created several similar files (filename and filesize), compressed it to bzip, normal in 7z and then spanned it in WZ and works fine here. It probably is more specific that simple spanning on bzip does not work.



  • I just recreated the problem using the rfdc tool I referenced in this post:

    I then used 7zip to create a zip file using the settings mentioned earlier in this post. Next, I used Winzip to split this zip into DVD sized files. Finally, I used PA to unzip the split zip. PA eventually hung trying to unzip the split files.

    Hopefully you can recreate the problem using these steps.

    Let me know if you have any questions.


  • conexware

    reproduced! 🙂



  • Great!


  • conexware

    PA 2010 11.60.25 is here:
    http://bit.ly/4snT7H

    check it out and see if it solves your issue.
    It seems that split bz2 zip files were not properly supported!

    thanks



  • Works!

    Many, many thanks.


  • conexware

    @dragon57:

    Works!

    Many, many thanks.

    thank you for reproducible reports 🙂



  • Luckily I have ocd when it comes to details :).
