It looks like you've got a repacked game file, specifically "Trinity Fusion" version 1.1, with a MULTi9 language pack, and it's a FitGirl Repack. I'll provide a general guide on what this means and how to work with such a file.
Use or WinRAR to unpack the .rar file(s) into a single folder. You will see these files: Trinity Fusion -v1.1- MULTi9- -FitGirl Repack-
