Quote - The standard zip-extractor on the Mac doesn't work with this file.

I downloaded the file and got a normal zip-file. Then I tried to extact it with the standard unarchiver in Mac and instead of unzipping the file it made a file with the cpgz ending.

Stuffit Expander extracts the downloaded zip-file fine.

if you are using Safari as your browser:

In Safari's preferences, first tab - general: do you have the box at the bottom checked? Mine says something like "Open safe files after downloading". I don't know the exact words in English as my Mac speaks Swedish. If you do, this may be the reason why you are getting a file with the ending cpgz.

I tired Stuffitexpander. and got the same stupid result. on the off-chance I was missing something I rn both the original posted .zip file as well as the unarchivd file and got nowhere with either.

I even went to the site Garee sent me to Google Search to find, and downloaded TheUnarchiver3.0 which is supposed to be able to open all files including the one with the weird extension. I installed it and it repeatedly crashed when i tried using it.

I don't use Safari prefering the newest version of Firefox but though that offers the same option I turned it off so I can use my advanced version of StuffitExpander with all the darn bells and whistles I purchased when i got this computer.

So it's isn't as if i haven't tried all this stuff even before i posted here. I came here hoping to find a solution I may have missed.

Thanks anyway for your help.
