Audiovox VME 9415 Mode D'emploi page 111

For example, a medium with the following folder/file hierarchy is subject to Folder
Search, File Search or Folder Select, as shown below.
The VME 9415 player will only recognize three folder levels and does not display
folders containing only other folders. In the example above, the unit will display
folders 3, 4, 6, and 8, but not 2 and 7 since they do not contain any tracks directly.
Folder 5 is not recognized at all since it is at the fourth level.
