On the application interface I see Speeditup Free 4.95 and in the download folder I see Speeditup Free 4.0. What is the difference and which is the latest version?
The program updates itself to the latest version when you install it. The latest version is Speeditup Free 10.01 and you can check Software Informer review page of the product in order to find more about it. In the left side of the review page you can find information about all versions of the application.
