What is a SIT file?

A .SIT file is a StuffIt Compressed Archive file.

SIT files are StuffIt Compressed Archive files that have been created by the StuffIt software application by Smith Micro. It is a common file format that is used to compress files on Macintosh computers. This allows users to take large volumes of files or single files with a large file size and compress the file or files into a single file archive.
