EDIT: This is the 380 2gig Audiophile update.
Before installing 380 I noticed there were Holds folders 269,270,275 in the root of the Direct Input/Library folder "G:\bb\RealTracks\Direct Input\Library\" they have the wav files only in them then after installing 380 the same folders in G:\bb\RealTracks\Direct Input\Library\Holds have the wma, bt1, xm2 etc.. in them.
