Or does it depend on metadata, not just the presence of books in that location?
No compatibility. CC sees only the books that it put somewhere. It does not scan for books already there. Scanning is a complex process involving attempting to read metadata out of books. This isn't too hard for epubs, but the complexity goes up very fast after that.

If the books were put in the folder by calibre then it is in theory possible for CC to read the .metadata.calibre file and get the metadata necessary to populate its database. We haven't done anything with this idea because we didn't think it would come up often.
