The folder hierarchy can be visualized via the TBrowser . The Root folders hierarchy can be seen as a whiteboard where objects are posted. This whiteboard facility greatly improves the modularity of an application, minimizing the class relationship problem that penalizes large applications.
Pointers are efficient to communicate between classes.
However, one has interest to minimize direct coupling between classes in the form of direct pointers. One better uses the naming and search service provided by the Root folders hierarchy. A TFolder is created by invoking the TFolder constructor. One can search for a folder or an object in a folder using the FindObject method. FindObject analyzes the string passed as its argument and searches in the hierarchy until it finds an object or folder matching the name.
