Resource Manager Interface - Tree Control
      A tree control allows you to view the hierarchy of folders
      and the contents of folders.
      
      To view the hierarchy of the folder and its sub-folders
      located in the digital file, do one of the following:
      
        - Click on the desired folder in the left pane of the
        screen. The contents of that folder will display in the
        right pane.
 
        - Click on the plus sign in front of a particular folder.
        If a folder does not have a plus sign in front of, it means
        that the folder does not have any sub-folders. It does not
        mean, however, that the folder does not have any contents.
        The sub-folders will be displayed in the left-pane under
        the main folder.
 
        - Double-click on a folder or sub-folder, and the
        contents of that folder will display in the right
        pane.
 
      
      
      To view the contents of a digital item, double-click on the
      digital item in the right-pane.
      
      Navigate up one folder level from your current location by
      clicking on the "Up one folder level" button . This will move
      you back one level in the tree control.
