510                    Thuban provides a path recovery feature: If a (shape) file referenced
511                    in a Thuban session cannot be found at the specified location, the user
512                    is prompted a file dialog. Here a new location can be selected for the
513                    currents layer data source. Cancelling the dialog removes the layer
514                    from the session. If a new location has been selected, Thuban checks
515                    this again, if further layers data sources are missing. The user is
516                    informed about this and can accept or cancel the suggestion.
