I'm not sure if this is the correct place to post this question, but here it goes. I have many jobs currently creating quite a few root files. I have the files numbered so I can read them using a simple for loop. However, some jobs haven't started yet and some are still running. I would like to read only the files that exist and are closed. I've tried something like... Int_t i_last=272; for(Int_t i=1;i<=i_last;i++){ char fileName[60]; sprintf(fileName,"$NTUPLE_DIR/B/BJpsiSkimFeb14%s_%d.root",name,i); if(g.Open(fileName)){ TFile f(fileName); ksMassNoCuts->Add((TH1F*)f.Get("h1d3")); } } g.Open(fileName) still returns true if the file does not exist. I've searched through the root page and have had trouble finding anything that will allow me to assess the state of a file without explicity trying to open it. Any help would be greatly appreciated. Thanks, Alex.
