I have a separate, external drive for iTunes and create all of my ABB projects there; then, while rooting around my local drive, I find that in my iTunes folder the is an "AudioBook Builder" folder and in it are copies of what appears to be final audio .m4b files, i.e. the finished product of a build.

But going into iTunes and clicking on the same .m4b file, Show in Finder, it has the exact file in the folder I'd expect it to be in (on the external iTunes drive).

The point here is it appears two copies of the final .m4b file are being kept, can I safely get rid of the one(s) in the "Audiobook Builder" folder under iTunes on the local drive?
