After downloading and installing the software in our system, files with the .SIT extension should be automatically associated with the new application. With this association, the file can be opened by double-clicking the mouse. If for some reason we still cannot open the file with the .SIT extension, we still have one method. It involves the attempt to open the file from the installed application. Choosing from the menu "FILE", we perform the command "Open" and the explorer window we select the file we are interested in, and then we confirm by pressing enter. This method is more time-consuming, but enables us to definitively state whether we use the correct application to open the files with the .SIT extension. If we are sure of it, we then use the extended reference menu (shift key and right mouse button) and by selecting "Open With", we select the appropriate application and we permanently connect it with a file with the extension we are interested in.
