You can choose whether the Project Window displays your project location names as regular case text, or as file rule names, meaning in MEL nomenclature, by toggling between View in Nice Names and View in File Rules. For example, the nice name Source Images displays as sourceImages for its file rule name. By default, the Project Window displays projects locations as nice names (View in Nice Names).
