Accessing your briefcase is very similar to accessing your workspaces, i.e. you are presented with a listing of your briefcase folders in which you can navigate, inspect details and possibly change details.
Note that you can delete folders from your briefcase using the action [Delete], but you cannot add folders to your briefcase at the mobile user interface. Also, synchronization of the briefcase contents is only possible at the standard user interface at your PC (also see 13.7.2 Working with the briefcase).
