If it were my PC, I think I would move (not copy) all the BIAB files in whatever folder has the BBW.EXE file, to C:\BB and make sure that under the C:\BB folder there were RealTracks and RealDrums folders. But I wouldn't try it unless you are comfortable navigating and had a utility program to move, not copy. In case you want to try it, I use Total Commander but there are a number of other good ones out there. If you don't have a lot of Real Tracks, which are comparatively the only really large files, then copying everything is OK. Erase the old folders when everything is tested and working in the new location.

Your last sentence is bothersome, though. You can set Real Tracks and Real Drums to work from locations other than that where BBW.EXE is located, and they are set separately in the same general way in the Options, Preferences area. If you have one set correctly, and the other matches, it must mean something got moved somewhere it should not be. Please look in Options, Preference, RealDrums and in Options, Preferences, RealTracks and see if the checkbox for "Use a Custom Folder Location" is checked, and if so, tell us what it says there for each.
