From the developer:
The function of this program is to help all those who want to have a "clean" environment for MSTS. The main function is, of course, to make consist building an easy task, but since there are so many files involved, there are chances for some to be missing or to contain errors; therefore the feature of performing tests was needed. One of the main things it does, is to check if all needed files are in the right place.
You may want to check out more software, such as PC ScanAndSweep, Advanced WindowsCare Professional or Desktop Maestro, which might be similar to ConBuilder.
