Wazza CDT is basically copying 3 times.... (makes 3 actios)
cdt swaps back and forth between 3 parts. Spitweaker asks for only 2 partitions, so I am assuming it just swaps back and forth between the two.
....if you are too lazy (like me) or do not feel like making the files for wazza, you can have spitweaker make them for you. run spitweaker the 1st run, then after that, the files are already there. All you have to do is drag/drop. wazza done!
