The Unarchiver is designed to handle many more formats than Archive Utility, and to better fit in with the design of the Finder. It can also handle filenames in foreign character sets, created with non-English versions of other operating systems. I personally find it useful for opening Japanese archives, but it should handle many other languages just as well.

It is very simple to use and install - simply copy it into your Applications folder, or whereever else you might prefer, and then set it as the default program for archive files. This can be done either from the preferences panel in the program itself, or in the Finder.

Supported file formats include Zip, Tar-GZip, Tar-BZip2, RAR, 7-zip, LhA, StuffIt and many other old and obscure formats. See the supported formats page for a more complete list of supported formats.

Download it now from the Mac App Store! The Unarchiver is completely free, and will always remain free. If you appreciate the hard work that has gone into writing it, you can use the buttons below to donate and support the developer.
