If your external hard drive has enough space to hold all of your songs, I would recommend moving the song files from your internal drive to the external drive to free up space on the internal. Otherwise your system will get extremely slow. Move them by copying them to the external and then delete them from the internal. That way you won't lose them if an error happens to pop up.
If you do the above, then the best way to add them would be as folows:
- Delete the song.mdb and the backup.mdb files in the database folder under Hoster.
- Open Hoster and add the external drive location when the program requests it for rebuilding the database. This will rebuild the database and add all the KMA files.
