Another technique...
You can use Rename, Move & Copy files via MC's Explorer to also move the files that are not imported into MC. For directory moves, this is easy enough. For files renames, you'll want a rule to exclude renaming the file name's of files such as Folder.jpg (and any other files that should not be renamed).
Select any track from the album, and then Locate On Disk (inside Media Center). This brings you to Explorer view where you'll see all the files. Select them, and bring up the Rename dialog. You should see all the files in the directory. Rename away.
