Found another winzip type app: "Windows/Linux: Open-source file archive manager
PeaZip creates and extracts files from a number of the most popular archiving formats, including ZIP, RAR (read only), 7Z, and more. Our nod for file archive managers normally goes to previously mentioned 7-Zip, but with an attractive, user-friendly interface, customizable right-click options, and a standalone portable version you can add to your thumb drive, PeaZip has a charm worth checking out. PeaZip is free, Windows and Linux only."
