There is only one file type that uses the .MSCT extension:
MOPEKS Script File
File created by MOPEKS, a program that generates multiple programs run by its script to use each other to solve problems; contains script data, which is accessed when the file is clicked to conduct MOPEKS to run the appropriate actions.
When you open the MOPEKS application for the first time, a window will open asking if you want to make the MSCT file associated with the MOPEKS program, click.
MSCT files are located in C:\MOPEKS\Factory\Scripts.
NOTE: Other MOPEKS associated files include .MPKT, .MTHD, and .MTXT.
