Great all around program for opening zipped archives. It will open most any type of archiver program you throw at it. Always one of the 1st programs I reinstall after reformatting my computer.

Hard to beat this general, all around zip program. Don't know of any compressions it can't uncompress plus it can compress into several different formats. And now it's in 64bit. This one's a keeper.
