Notes about the SIT file extension:

To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

The SIT file type is primarily associated with 'StuffIt' by Smith Micro Software. StuffIt provides compression solutions for your Mac or Windows PC as well as your PDA and SmartPhone. Allume Systems, Inc. has taken over this product from Aladdin Systems, Inc. Smith Micro then acquired the product.
