Use the Tools menu Build Songs Database command to rebuild as George mentioned above. You should be able to click and drag your KMA files from the Hoster/Songs folder to your destination one. You don't need to keep a copy in the /Songs folder. Then, also make sure in the Build Songs Database command that you click the Add Folder button and select the new folder your other drive to add here. Otherwise, when rebuilding, it won't find that drive/folder.
