[ROOT] TFile in TChain

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?


Thanks,
			Paolo
