Creating a root file that is the combination of many root files

Hi all,

I am trying to create a “daily” root file with all the data taken for a certain day, at the moment I have many tiny root files, inside hourly folders. I am very new to ROOT and am not sure how I can do this, could anyone help me?

In other words: I need to loop through the folders that exist and create daily “short” files (i.e. a single root file that is the combination of all the root files) and put them into a new folder.

Try the standalone executable distributed with ROOT:
