How to Extract SIT or SITX in Windows


StuffIt is a file compression program typically associated with Mac computers, but available for both Mac and Windows operating systems, that outputs SIT or SITX files, depending on what version of the program you're using. Because Windows users are more accustomed to receiving files compressed in a ZIP package, receiving a SIT or SITX file can throw them for a loop. However, Smith Micro, the company who built the StuffIt program, makes a free StuffIt Expander for Windows program available that you can quickly install on your machine and use to extract the contents of SIT or SITX files seamlessly. The time it takes to extract the file depends on the size of the file.

Most people use a 32-bit operating system, but you can check your operating system type in your computer's System Properties window. If there is no bit type listed next to your operating system in the System Properties window, your operating system is 32 bit; if you're using a 64-bit operating system, it will say something to the effect of "Windows 7 Home Edition (64-bit)."
