Hehe... no, it's even easier than that. There actually are quite a few "extraneous" directories, but CM doesn't consider them -- in fact, it actually doesn't even look at the filesystem at all. It simply looks at the books database, and for every book there, it uses the fully qualified path to the file to determine (and create) collections from that.
That also means that you can create as many folders as you want - if there are no books in them, they won't be mapped to collections
