Assuming I understand, they are NOT in the libraries folder. Is that correct?[/quote]
Correct. They are in the "src" subdirectory of the sketchbook directory. These are libraries used ONLY for this one sketch, putting them in the libraries folder would not make sense. I need the entire sketch, and its libraries, to be self-contained, so it can be easily handed off to someone else in a single ZIP file, without requiring them to install libraries somewhere else.
