PowerArchiver 9.20 (final) ZIP Extraction Bug

[welhaux]

PowerArchiver 9.20 is unable to extract both files in this archive. It will extract only the HTML file. It complains that it is part of a spanned archive, but it is not. Microsoft Windows XP integrated ZIP is able to extract the file

I reported this before but it isn’t fixed in 9.20 final!

its the ttf file thats causing the problem on testing with pa it sayes the s same error message above but if you test it and click on the ok button a few times it sayes archives is ok.

I even created a repaire archive and that failed ttf file was again the problem

winzip and winrar passed ok extracting these files.

must be a problem with the.

Hold on a moment WHAT ZIP UTILITY DID YOU USE TO CREATE IT. I JUST EXTRCTED THE FILES USING WINZIP AND THEN WITH WINZIP AND PA I CREATED A NEW ZIP FILES AND IT WORKED EXTRCTION OK SO IT CAN’T BE THE FILES UNLESS THERE IS A PROBLEM WITH THE ZIP BUT WINZIP SAYES OK TO THE ARCHIVE STRANGE.

hAS TO BE A PROBLEM WITH WHAT PROGRAM CREATED THE ZIP. hOWEVER FIXING THE ARCHIVE FAILS IT STILL REPRODUCES THE SAME FAULT.

It’s doesn’t appear to be a problem with DynaZip either because I had no trouble extracting both files with another app that uses the DZ library. It’s possible they’re using differnt versions of the DZ library though.

EDIT: The problem also exists with 9.20.04 (ie. beta 1).

It is an problem with newer DynaZip library, but I dont know what exactly is causing it… It has to be something very specific to the archive.

We are checking it out.

thanks,

how come pa 7.02 is ok extracting it.

If I knew, then I wouldnt have to be checking it

I have noticed i get a runtime error trying to extract zip files stateing
End of file or corrupt.

Then i get runtime error 216 at 004042EE

I hope this helps fix this or other issues.

[davidsplash]

any chance you can upload your zip file here to the developer can take a look at it

[davidsplash]

this problem is happening more and more when will it be fixed

Does that mean you have experienced the same problem with other archives as well? If so, let us know.

thanks,

[davidsplash]

yes but only with zip archives. i can not upload them here but they work with winzip and winrar

@davidsplash:

… happening more and more … i can not upload them here …

I use zip a lot every day and haven’t seen this error.

Can you identify how your files were created (which tool / options)?
Is there something common about the mix of contents (files/folders) e.g. also have ttf?

I dont think it is that common at all - I have been checking it while waiting for response from dynazip, and this particular file did not work for past 3 versions of PA, and it is the only file I know so far that doesnt work with PA, without any proper explanation.

i have one more but cxan not send it to you due to its contense

[cyberblob]

Here i found one that causes my error that i can release.

Omniquad AntiSpy DefMain.zip will cause the same error i get with my file.

If you right click and try to extract the archive it will fail to extract the archive fully
If you open the archive then select all contents and drag them to a folder it will error with text "Unexpected end of Zip file. probably the file is corrupt or missing spanned file.
Then you will notice all file in zip are gone then in the archive.
Then close powerarchiver and crash you are there.

I have a zip archive containing 3 files: an exe, html, and txt. I attempt to extract the exe to a shared folder. It goes through the extraction process, but the file is not visible in the destination folder. If I extract again, it confirms whether I want to overwrite. i.e. the file is somehow there, but not accessible or visible. I have tried extracting to various folders with the same result. In each case I am opening the archive before processing. I tried the same archive with WZ, and it extracted OK.

Check file attributes in the archive? Thats something different in any case…

@cyberblob:

Omniquad AntiSpy DefMain.zip

Is the name correct? I went to http://www.ominquad.com
On their download page AntiSpy file is named TSAntiSpy.zip and extracts OK
Also tried TSPassword.zip - also extracts OK.

I cannot see a DefMain.zip there?

[cyberblob]

Yes the software is correct.
http://www.omniquad.com/TotalSecurity/TSAntiSpy.zip

Download their antispyware solution. then install it
Update the signature database then look C:\Program Files\Omniquad Total Security\AntiSpy\Sig\Defmain.zip it is their signature database.
