    Their are four zip files, z01, z02, z03, z04 and I'm trying to open only one that I've downloaded but when opening I'm getting a message:

    Unable to unarchive "File Name.zip"
    (Error 1 - Operation not permitted.)

    Is their a known trick to extracting just one file without having the rest?
    Possibly a Terminal or linux coded way?

    I've tried the following software: Archive Utility, Stuffit Expander, Winzip Mac,
    Rar Expander, Zippeg.

    Nevermind. I totally misunderstood the question 'til GGJstudios deciphered it.

    That's because you can't open just one of the files. Think of it as a single zip file with 4 parts. You have to have all parts present to make it a valid file and unzip the file. Then you can extract a file from the zip archive.

    Go to the Finder and make sure that the files are in the correct order (i.e. sort by name). Then open a terminal window, and enter:
    and drag all the zip parts in the terminal window. The temporary result should look like this:
    Now specify the ouput file via:
    and hit the return key to execute the "cat" command.

    Here is a full example for my disk "TestDisk":
    The last example joins the parts of the zip archive in the correct order (this is important), and saves the .zip file on the disk "TestDisk". You can use now a program, like StuffIt Expander (it supports also encrypted .zip archives) to decompress the .zip file.

    That won't help the OP, since they don't have all the files. They must first download all the files, then they can unzip with an unarchive utility. There's no need to use Terminal.
