Dana,

Yes, unfortunately the file structure does not match up the the Set numbers...

If the structure were more like:

RealTracks
-----> Set 1
--------> Accordian Rythm Pop Ev 80
--------> Real Track 2
-----> Set 2
--------> Real Track 1
--------> Real Track 2

...then it would be easier to do what you want. But you should be able to say, "I'll never use Accordian.." etc and move that folder... "I'll never use Pedal Steel Guitar"...move it etc.
