Hi Brett, There is a fundamental difference between TFolder and TDataSet. TDataSet is an interesting container. TFolder is NOT a container. It is a white board where you post references to your objects or containers. TFolder has an additional functionality: From a TFolder, you can generate automatically a TTree (or several TTrees).
