Crazycarl,
Here is what I have copied and pasted out of the manual on this:

Steps to Build the Songs Database

1) Click the Tools menu Build Songs Database command.

2) In the dialog box that appears you will see a Songs source folders list box. Add the folders you have created and imported songs to (or moved .kma files to them from any other folder) and their .kma files will also appear in the newly built Songs Database.

If you want to import your kma songs into your D drive, then create a folder there like, D:\Hoster Songs. When you click the Build Songs Database button it will add only the .kma files found in the D:\Hoster Songs folder to the new Songs Database.
Click the Build Song Database button to create the Songs Database. Clicking the Cancel button terminates the rebuild operation.

3) Make sure that you have the "Song Database Destination folder" set to C:\Program Files\Micro Technology Unlimited\Hoster\Databases or your songs will not show up when you are finished rebuilding the Songs Database.

The new Songs Database is built from songs found in the specified Song source folders, and written in the selected Song database destination folder.
