What Is SIT File on Mac

SIT file is Stuffit archives or folders that are compressed and make downloading sets of files more accessible. These files open automatically when they are downloaded. On the older mac versions, the downloads were usually single .sit files. On the newer Mac versions, you can use third-party applications to open SIT file on mac. 

These files usually belong to StuffIt by Smith Micro. The Smith Micro StuffIt file compression and archiving software was made in 1987 and became popular because of its high compression ratio as other formats at that time performed less than it.

StuffIt also allows for creating email attachments which in turn help facilitate access, documentation transmission, and data security. On top of that, it secures archive documents by encrypting important information using SIT file. You must remember that SIT file is not prone to viruses, unlike other file formats. 

Although StuffIt was originally for MacOS, with time, it became compatible with other operating systems, including Windows, Linux, and Sun Solari.
