"Error 1 Operation not permitted" no longer!

While working on an animation I wanted to include clips from work done and archived in 2008. Other stuff in .zips from that same project opened without a hitch. There was one fat juicy .zip that refused to open, even after trying Terminal and Pacifist. Grrrr.
I checked out the App store and found this miraculous App, The Unarchiver. It worked like magic. The zip unzipped. All the files in it were just perfect - nothing was corrupt. Thank You, I’m so grateful this App could overcome the Error 1 and unzipped my stored work!
