    Well.. I'm fairly new to Macs. I used a PC my whole life, and switched over about 2-3 months ago when I purchased my MacBook Pro. On my PC, I download winrar to unzip files. But I noticed that winrar is a windows program, and I don't know which program I would use for my Mac.

    I was under the impression that with Macs, when you download a file they automatically unzip themselves (silly me :_P haha). So if anybody can help me out, I would appreciate it. I hope I'm not too much of a pain in the butt.

    Haha. I've tried that. But all it does is duplicated the zip file. I'm sorry if I'm missing something, my awareness with computers is not all that great. I commend anyone who can be patient with me.

    it basicaly "mounts the zip file as a drive" it will show up in finder and you should be able to open it ..

    the reverse is to select files right or cmd-click them and select create archive or compress im not sure of the wording

    The only way that's possible is if the zip file you're clicking contains in it only another zip file which is identical to the original. So it's not duplicating the file, it's unzipping the file and leaving the file that was contained within, which is another zip file. (which is a bizarre and pointless zip file to create in the first place.)

    Where did this zip file come from?

    It's a photo pack from www.deviantart.com . There were comments on the file of people downloading it and being happy with the pack. It's probably something that I'm not doing right rather than it being a faulty file.

    When I "open"/double click it, the duplicated file is the same name as the file but with .zip.cpgz at the end rather than .zip. This happens with every zip file I download, by the way.

    I appreciate the help guys.

    ^ try removing ".zip.cpgz" and adding ".dmg".

    That's the unzipped file. Only the letters after the final period actually count towards describing what type of file you have. The unzipped file is that whatever.cpgz file that appears after you dobule click the .zip file. I have no idea what a cpgz file is, but that's the file that was contained in the zip file. Search google for .cpgz

    EDIT:

    What happens when you double click on the cpgz file?

    After trying that. A pop-up came up when I tried to open it saying "The following disk images failed to mount" with the name of the file.

    What happens when you double click on the cpgz file? (without renaming it to dmg)

    It duplicated the file for the second time. haha

    So is my Mac just acting up, or am I doing something wrong? Because if its supposed to be as simple as me double clicking it there has to be something wrong.

    it has something to do with the way that the file was archived by the original person.

    did you try stufit expander it should be free

    Well, when I try to change the duplicated zip file (.zip.cpgz) back to a .zip, it doesn't allow me to because it says there is already a file with that name (since that was the name of the original before it was duplicated). I then deleted the original so I could change it. But when I tried opening it as you guys suggested it still duplicates. Nobody else has this problem?

    Download and use the free stuffit expander program, as has been advised several times already. This is just a weirdly compressed file causing problems, you'll probably never encounter another zip file that doesn't unzip after a double click.

    The download button is on the left side of the page.

    i think the file is just corrupt as my Quick Look zip viewer can see the images and so can Pacifist but when i extract an image with Pacifist it says the checksum is invalid and then Preview cant open it and says its corrupt.

    Well I downloaded and unzipped the file just fine on my PC (I still want to figure out how to do it on my Mac because its a pain downloading everything on my PC and bringing it to my Mac). And as I said it happens with every zip file.. not just this one.

    Whats the deal with that stuffit program? Is the equivalent to winrar/winzip? If so, should I download it? Its free?

    Again, thanks in advance.

    Thank you so much. It says I have to pay for it at that site though.
