+on the player.  You can filter the directories which are scanned by
+creating a file called \\* 
+\fname{/.rockbox/folder\_advance\_dir.txt}.  
+Only the directories in this file and any contained directories
+ will be scanned.  You can have up to 10 directories ignored by the 
+ scan by placing a minus sign before them in the list 
+ (i.e. \fname{-/CDs} will cause everything in the \fname{/CDs} 
+ directory to be ignored.).  If you just want \fname{/CDs}
