Ciao rooters, when you build up a chain adding many root files like as in case of: chain->Add("*.root"); you lose the memory of the TFile you are pointing to. In a Loop on the chain, I know that, using LoadTree, one can be aware of the moment in which ROOT goes from a TFile to the following one: Int_t ientry = LoadTree(jentry); because ientry is equal to 0. How can I get the information about the name of the current TFile? Is there any method or "workaround" to do it?
