Winzip error

1,159 Views
Last Modified: 2007-11-27
I am using winzip to compress files. after it is done I can right-click on a zipped file -click explore and see the files.
But some zipped files when I right click on them then click explore it throws a message: "The compressed(zipped) folder is invalid or corrupt"
I tried several times to zip the files and it throws the same error.

any idea?

thanks

Let's try cleaning out all the extraneous garbage that collects in Windows.  Download and run CCleaner (www.ccleaner.com).  This also includes a registry cleaner.  Run the cleanup and registry functions.
Reboot and do a defrag.
If your problem still occurs, uninstall WinZip, then reinstall.  

Question - is your disk NTFS or FAT32?

Author

Commented:
It's NTFS

Commented:
The disk full error sometimes would occur on FAT32 partitions.  Not the case here.

Try the cleanup and reinstall and let us know.

Waiting for your response to my last suggestion.  Did it work?  If not, exactly what errors are your getting.  And what size zip files?  Please provide answers to our requests for more information so we can proceed.  Thank you.

initially the error was:
Possible cause: Disk Full or system limits exceeded.

Now I still can zip large size files, but when I open(explore) the zip file there few columns there and 2 of them shows packed size and the other one just size.

so the 36 gb file when it get zipped the packed size shows  a little bit over 2 gb and size show a little bit over 4 gb.

I thought the same way.

36 to 2 or 4 didn't seem right, but when I Unziiped the file it extraxted 36 GB , so it works fine.
