7zip archives and more in a click
Stuffit Expander is the most widely used expander and decoder utility on Mac.
Although there are now several other options out there, Stuffit Expander has certainly been around as long as any and is a powerful tool for anyone that works with multiple file formats. It's easy to use supporting the dragging and dropping of files into the Stuffit Expander drop box which instantly unarchives files for you.
Stuffit Expander supports over 30 different archive formats including StuffIt, RAR, 7zip, split and segmented archives. It can even be used to decompress archives encrypted with 512 and AES 256-bit protection. You should be aware however that Stuffit is quite a large application despite its simplicity - it installs a lot of components along with the program that some may find bloat their system somewhat.
Stuffit Expander is still a powerful and effective tool for handling almost every archive format out there.
