What is StuffIt, and how do I decode Stuffed archives?
StuffIt is primarily a Mac OS format for file compression and archiving. Unlike most other standards, it was designed with the Mac OS dual-forked file structure in mind, and has the capability to store several files and even entire folder hierarchies in one stuffed archive.
Although StuffIt is still sometimes used in Mac OS X, Apple and many other developers now distribute programs as disk images instead. In 10.4 (Tiger), Apple stopped bundling StuffIt Expander with the operating system, though it is still available for download.
Stuffed files can usually be identified by the .sit or
.sitx extension at the end of their
filenames. Safari, Firefox, Internet
Explorer, and other Internet applications are able to
unstuff and decode archives with the help of StuffIt Expander.
