Use two TFiles at once

ROOT

Is it possible to use access two TFiles at one time? I am trying to pull histograms out of two files. The script is attached below.
Thanks!

Instead of gROOT->FindObject, do

TH1 *hist = (TH1*)fFile->Get("siCsi/histo_name") or

TH1 *hist = (TH1*)fRefFile->Get("E/hist_name")
