Re: [ROOT] File size

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.
