File Extension SIT

What is a Stuffit Archive File?

Archive files created by the Macintosh version of the program StuffIt use Files with the SIT file extension.

Raymond Lau developed the StuffIt program in 1987. At the time, Lau was just a high school student. The company Aladdin Systems was later formed to handle the development and distribution of the program. Smith Micro Software is currently handling the software. Smith Micro continues to develop and support the program.

Archive files with the SIT file extension can be used to store more than one file. These files are encoded so that they can be saved as one file. Archive files can also be compressed to reduce their file size. An encoding process is used to translate the data in the files into a separate format. This often involves the use of algorithms to determine which characters to replace and what characters to replace them with. Groups of data in the original format are translated into a new character. This allows the file to become smaller in size. The type of algorithm or encoding process used is saved with the archives so that programs can decode them later.

StuffIt provides users with several encoding and algorithm options to create files with the .sit file extension. The program includes support for other archive formats. It is able to decode and update archives created by other software. Stuffit can also save archives in a number of file formats. However the SIT file extension is the default file extension used for files compressed and archived by Stuffit.

Files with the .sit file extension can be created by a number of compression speeds. StuffIt allows users to choose the settings at archives are created. The StuffIt program can decode archives with the .sit file extension. The application checks the archive for the compression method used to create it. This same method is used to translate the information stored in files with the SIT file extension. Once the archive has been decoded, the files it contains are translated to their original format.
