Windows 7: I can't open any zip files

I can't open any zip files

It started happening a couple of weeks ago. I could not open any of the zip files I downloaded from Dropbox for example. I thought my computer was acting up and it was time for a nice fresh re-instalation and re-formatting. But I still have the problem. I downloaded a zip file, and tried opening it with Jzip, The Extractor and 7zip, but it keeps saying "jzip does not support the file format of the file you are trying to open".

Help me, please?

Can you attach one of the zip files in a post here so we can look at it, or give us a link to it in your Dropbox Public folder?

Sound like the file extension had been renamed.

The Dropbox folders that I can't open, are the ones they zip for download. This is the link to another folder, not from Dropbox that I cannot unzip.

Who zips it, Dropbox? I've never downloaded more than a single file from Dropbox so if there is an automatic zip I've never run into it.

Your zip file is definitely bad. I just tried downloading the Photos folder from my Dropbox account and it automatically zipped it. Once downloaded, I can browse it and unzip it, so it looks like there is a problem on your end somewhere.

Can you try a smaller set of files to download, see if that works? Scratch that, not Dropbox specific I see. Who/where did you get the file from? It is definitely corrupted or not a zip file.

I only download these files either from Dropbox, and they are compressed by them. The others I haven't been able to open are files received through sites like WeTransfer, etc. I am at a loss...

Try running Firefox without Add-ons.

Click on the orange Firefox drop down at top left, select Help then Restart with Add-ons disabled, see if that works.
Try it with IE, see if that works.

Also you can right click on the file and say open with to choose your unzipper.

Hi Labecs,
In your last post >> ive got other probs with IE<<, this is beginning to look like a malware/virus problem,
would suggest you run MBAM and your AV's and pop over to the am i infected sub-forum.(system security)

Another way to open ISO files
If you occasionally have to open ISO files, but don't want to download a third party problem (certainly not one called demon or devil or whatever), here's one way to do it: in XP Mode, one of the options is to mount an ISO image rather than the CD-ROM drive at startup.
