I also use this application and it's really great. You can't go wrong with that. It's free and easy to install but it seems that it doesn't work on all devices. However, just try and see if it fullfills your needs.
the other bunch of zip fils are probably .cab file. Confirm it by opening and it you see a lotta files which dont make sense then its cab :P
Copy the cab to your x1 and run it from there
