Zipped important files and now Winzip won't unzip them

Recommended Posts

I'm having trouble extracting/unzipping an important Winzip file, heres the error messages:
WinZip encountered problems during this operation.
Would you like to view the detailed results of the last operation showing the specific error(s) encountered.?
YES
Extracting to "C:\Documents and Settings\Administrator\Local Settings\Temp\"
Use Path: no Overlay Files: yes
Extracting UVIDS.zip
I/O error - unable to read from zip file
Unable to authenticate file. Either the Zip file has been damaged or the password is incorrect
Unable to create C:\Documents and Settings\Administrator\Local Settings\Temp\UVIDS.zip:
The size of the extracted file (1287651328 bytes) does not match the uncompressed size (1987321916 bytes) recorded in the zip file
Additional Notes:
- Im logged on Win XP as the admin
- The password for the file IS correct.
- I deleted the original folder and files.
- I attempted this extraction umpteen times.
- To create this zip file, I zipped all the original files into one folder, and then zipped that folder again so you could not see the original file names. You cannot see the original files, only the zipped foldercalled UVIDS.
Please help me unzip these important files.

All you can do is try unzip tools that have some form of error recovery built in.

 

7Zip is good to try and brute force t, you might find you can 'explore' the ZIP file, and extract all but the damaged single file.

WinRAR is usually OK at repairing RAR archives, i've never tried it on ZIPs, but worth a shot.

 

Otherwise, maybe make a virtual machine, and a copy of the zip file, and start trying every piece of spyware and adware on cnet that claims to fix zip files untill you (maybe) find one?

They're a real pain to recover IMO.

try the pw with caps enabled just in case

maybe running a full scandisk on the drive is worth a shot

Why bother? It's another fake problem with a malware link pending.

Apart from what the others have said stop unzipping to C:\Documents and Settings\Administrator\Local Settings\Temp\

Unzip to a directory you know you have full permissions too EG documents.

Also as mentioned try 7zip. http://www.7-zip.org/

Get winrar as that seems to be better :) www.winrar.com

Also with regards to recovering the data either use runtime recovery tools which you can use for free, but make sure to write the recovered data to a different partition or to different media so you don’t over write the data you are attempting to recover.
This site should give some options

A lame YT video that shows an installation of Winzip with convenient link in the comments to yet another Repair Toolbox page.
