Regarding moving files, always check the forums, including Producer and Studio, first to see if the particular program/files move will cause problems. There's 5 people (including me) that tried to move Dimension LE sound files to another drive and got screwed. Even the "Dimension LE install fix" sent by Cakewalk Support has problems re-installing. It says "Beta version expired. Please destroy..."

I have a feeling some "sound file" programs like Dimension (as opposed to pure midi programs/synths) might be more susceptible to problem moves.
