wait a second! i can't even think of moving/copying folders because i have in many cases some files which are not actually managed by mb such as artworks, pdfs, etc. so i'm really fine with actual folder structure and won't mind about names of the folders.
Just use the "also move remaining non-media files" option and those files should move with the rest of the album
what happens when u have some albums which are multiple cds in one folder and multiple cds in separated folders? i guess that's my greatest problem, that folders can be quite messy but all songs of all albums are every and each
in their respective folder or at least so should be.
