Merging multiple root files into one

Hello everyone,

I am trying to merging multiple files into one, in every root file there is a tree having some branches, every branch is an array of the object TClonesArray. Do you have any suggestions to effectively merge these files?

Best,
Jiawei

Try hadd

 hadd --help

(at the terminal prompt, not inside ROOT)
