firmware for Mac

I found it in finder - I did not open it - I dragged it to the clip.

Now it is just a zip file sitting there on the clip. I decided to open it and it became a sepperate folder called clppa.bin.cpgz so I then opened that and I got another seperate folder called clppa.bin

Do I keep opening these or was I not suppose to open those at all?

Sorry, but I am not all that computer savvy, I am rather late to the game.
