Can somebody help please
 

I'm having trouble with burning a game(Alien Front Online). I extract them(winrar) and get mastersplitter files. Then I put them together and get a file that my computer doesn't know. It's size is 138mb which is much smaller than any game i have burned before. I need help on what the next step is. I have tried fireburner, discjuggler, and nero but they don't reconize the file. I have looked on tuturiols that have been posted on previous posts but I can't figure it out. Can anybody help me or at least point me on the right direction?

If you expect help, you'll have to give us the extension for the resulting file. Otherwise, even we don't recognize it!

Is it a .BIN, a .CDI, an .ISO, an .NRG, or what???
