Yes you can. Under the edit menu, while the folder is open, click "select all". all the files will turn blue. Then right click on the files and selct copy. Next open the file you'd like to transfer the files to and right click again. Not select paste and it should begin to copy or past all the files. Depending on the number of KMA files you have this may take a while. After all the files are transferred, make sure you go into Hoster and rebuild the songs data base using the new destination.
I hope this helps you.
