Hi, when I use TTree::AutoSave() after each Tree::fill() the resulting rootfile is many times larger than in the case when I only save once at the end of the run. For example the Program `Event' in the `test' directory writes a 14.7MB Event.root per default. If I add `tree->AutoSave();' after each event the file is 156MB. It seems as if the "older versions" are not overwritten by subsequent AutoSaves. (There is also one additional tree in the rootfile for every save, as stated in the TTree description.) I played with the maxvirtsize arg of TTree:TTree() also, but the resulting intermediate dumps didn't allow a key recovery. How can I make the AutoSave procedure more effective? I don't want to loose to much data in case of a crash but i also don't want the program to crash because of a lack of disk space.
