Hi, In my experiment, PHOBOS, we separate every data file in one GByte chunk. Many of our physics runs generated 30-50GBytes raw data (how big is your file?) and we wrote a new files after 1 GB stack automatically. And a sequence number is automatically assigned to the file name, etc... I am not sure whether this functionality is useful for further ROOT development.
