7zip Problem



  • :mad: When unzipping a 7zip file (.7z) containing many thousands of files, PowerArchiver just shuts down part way through without extracting all the files. This is really crap. I can’t believe that this was tested. :mad:



  • can you post your 7zip file here. as for the comment i think its unfair. Well pa do not create the 7zipp dll that allows compnaies too extract or create 7zip files, so it most proably is a 7zip dll issue. Its a new format and is being developed. Thanks for reporting it but don’t blame pa as they have the best support for it outside of the 7zip file manager… Can the 7zip file manager work ok on your 7zip file if so it could be a adll or pa problem. which program created the 7zip file.

    To give no details of how you created it and what version of pa your using and what is contained in the file and not to upload it here for testing is vurtilaly imposible to determin the problem or even how to fix it. Bear this in mind when rubbishing something. What system are you using etc.



  • To add to David’s post, PA’s 7-zip support has been tested greatly by the many alpha users. 7-zip is very memory intensive archiving format. Like David said, without more information, it will be hard to help you. It would be helpful if you would post your system specs also.

    Additionally, there are not many error messages incorporated into 7zip. What could have happened would be something like bad memory, bad hard drive, bad motherboard, no space, no space in temp folder, and probably many other things as well :-).

    First thing I always suspect is memory since WinXP is behaving bad when it gets out of memory and just shuts off applications randomly and 7zip is using a lot of memory.

    I know I tested it with some maximum 12 GB sized file and maximum of 120,000 files inside of it and it all went ok.



  • Well guys, I know its not a problem with the 7zip file. How do I know this? Well, its simple really.

    The file was created with PA and contains 1,135 files and contains 8 main subdirectories and other subdirectories contained underneath these. Its certainly a LOT less than 120,000 files claimed to be tested. I can extract the files without problems using 7zip v4.13 Beta itself. I’m not even going to bother submitting the 7z file as any newly created archive with lots of files causes the same problem.

    I don’t think its memory issues, unless PA is getting its own memory usage stuffed as 7zip manager has no problems at all with extracting that, or any other, file. My machine is a P4 2.67GHz with 512MB RAM. Its running Win XP Pro.

    I don’t want to rubbish any program, and I do like PA. But when something like this happens, I don’t think you can say that its well tested. It might well be the 7zip DLL file, but if so, why doesn’t PA incorporate the latest DLL file and issue a new version of PA ASAP? I’ve known about this problem for a while, but I thought that it would be fixed in the latest version, but its been around since 7zip support was implemented.

    If you have had an issue with that since 7zip was implemented, then you should have reported it and it would have been fixed long time ago.

    If you do not report it, it will not be fixed.

    Now, you have to give us more information about the file since it certainly works fine here - we had 20 people testing that, and you are the first to report the issue out of more than a million of people who downloaded PA 9.xx so far.

    So please send us more info about the file.

    thanks,

    • Also - step by step on how to reproduce the issue would be great.

    thanks,



  • Well, I don’t know how much more info I can give.

    Step by step is this: I have maximum compression settings for 7zip archives and right click on a bunch of files and then choose compress.

    Have you guys heard of X-Setup Pro? Well, if you have, then install v6.6 and then go into Program Files\X-Setup Pro and compress all the files and subdirectories under that folder into a .7z file. Then try and extract these files to a different folder (c:\test) and you’ll notice that part way through the extraction, PA closes and not all the files have been extracted.

    Now that’s about as much detail as I can provide. If you follow these steps, I KNOW you’ll get the problem. I don’t understand how so many people haven’t come across the problem. I find it a little hard to believe, as I’ve had a lot of problems with extracting ANY .7z file that contains a lot of files.

    So you are compressing via shell extensions, are you extracting via them as well? What exact extracting procedure did you use?

    I did a quick test with folder with 3,000 files and everything worked fine, please provide more details, such as step by step reproduction of the issue.

    thanks!



  • this bug is in some 7zip programs like ultimatezip perhaps he used that and then powerarchiver as they look similar and they use a similar setup routine



  • @davidsplash:

    NO, I did NOT get confused. Besides, it’s pretty damn hard to get confused if you only have PowerArchiver and 7-Zip, and not UltimateZip installed.

    I tried doing this (with the latest X-Setup), and had no problems:

    PowerArchiver version 7.20
    X-Setup Pro version 7.1 (Eval) - this has 1040 files in 8 folders

    I performed the archiving and extraction operations using the shell extensions (right mouse click).

    I had the 7Zip compression set to ‘Ultra’

    Now I don’t know what to say to that. All I can say is that when I try that same operation, the problem occurs. But it does seem like there are numerous problems with the 7zip.dll file PA is using, so I’m sure I have a valid issue here.



  • I’ve been testing the latest version. I 7-zip (ultra) a file with 5 folders and 967 files. Tested the file, tested fine. Uncompressed the file without any problems.

    eh, there were no “numerous” problems with 3.xx 7z dll, not many people reported issues but there were for sure some memory issues that we were able to reproduce.

    Maybe on your computer there were more obvious than on others for whatever reason that may be. Only solution was the update to 4.xx dll which required our side of code to be completly rewritten which is why it had to wait for 9.5.

    So it does not matter that it works on some computers, we know it didnt work on some for sure, and it works fine in 9.5, so only few days more :-).

    closing the thread. thanks!
