What does the Unity DIF utility actually do?

Unity DIF is a comparison tool for Unity Pro project files. The latest Unity DIF is actually Control Expert DIF V15.2 and provides users with the ability to compare two different Unity Pro/Control Expert project files. It generates a report that identifies differences between the two projects. Users can review the generated report on-screen, save the report as a file, or print the report. CE DIF V15.2 can compare older Unity Pro project files, but it does require at least Control Expert V15.0 be installed in order to function.
