The Unarchiver Free

The Mac can deal with Zip files perfectly well, but what about those other archive formats that sometimes crop up, such as 7Zip, Rar, and StuffIt? Even if they’re much less common these days, The Unarchiver can handle those and many more exotic formats, and its preferences enable you to set it as the default app for handling as few or as many of them as you want.
