    how can I open .zip.cpgz file?
    Can someone tell me how to open a .zip.cpgz file? When I double-click on it, it creates a .zip file. When I double-click on the .zip file, it creates a .zip.cpgz file. Back and forth.

    There are many posts on this issue (Google search) but no definitive solution to it. It's a compressed Unix file, but that's of little help to you.

    If it's been sent to you as an attachment, ask the sender to repeat the process using a different file format, one that your Mac can open. Filejuicer File Juicer - Extract images from PDF, PowerPoint, Word, Excel and other Files on Mac OS X *might* do the job but that .cpgz compression is likely to be the obstacle.

    Which version of OS X are you using? Archive Utility supports .cpgz (or .cpio.gz) files just fine (and I know it has since at least Leopard, though I think it has for much longer). Perhaps the archive is corrupt. I'm not sure why it would be necessary to use both, but I made a test .zip.cpgz file and when I double-clicked it (in Snow Leopard), it completely unarchived it to the original form.

    Enough of this zip/cpgz fretting!
    It seems that the Archive Utility, when faced with a corrupt/illnamed file, even if called '.zip', will then zip it up** anyway as .zip.cpgz. This will unzip to .zip. Stuffit at least has the good sense to choke on the bum file and back out.

    ** or just rename it?

    Try sending the file to a pal with a Windows/Linux box to see what they can do. Probably also find it's damaged.
    Hilarious've got to laugh...

    Thank you so much!
    Thank you all so much! This was way easier than I thought!! All I did was De-compress the .bin file which turned into a .cpgz file. Then I just changed the name of the .cpgz file to .pdf and it opened to what I needed. Wow! Just try that and dont go crazy! It worked
