Burning .00 , or .01, .02 ...etc DC Files

I have a few DC games downloaded, and they're all in .00, .01, .02 etc. Format. Does anyone know how i burn these so they work?

[felt]

one file should be a rar file without 00,01,02 it should have a purple icon beside it, you double click on this file and it will start to extract it into a full image ready to burn. make sure the files if named kal.r00.r00 that you rename to kal.r00 just take away the last 00 and the full stop so it is just plain game.r00
game.r01 etc game just being whatever game you have. hope this helps
