Hi John C
As Bernie states, the 'Favorites' are a short cut to a particular file. It's very handy to organize sets of 9 songs. For example you might want to put short cuts to 9 'Sinatra' songs in one Favorite Bank. They will remain there as long as you do not move or delete the orignal file. If you move or delete an original file, then the 'Favorite' bank will not be able to find that file and therefore it will show as blank.
