Cloning of histogram and then writing into a directory

Dear Root Experts,

I want to clone a histogram and then I want to write it into a already created directory. I am trying to do it in a following way

 TFileDirectory MCPlots = fs->mkdir( "MC" );  TFileDirectory RecoPlots = fs->mkdir( "RECO" );  TFileDirectory Eff = fs->mkdir( "EFF" );  

 h_Lept_Eta = RecoPlots.make<TH1F>("LeptEta","Lep Eta",100,-5,5);  h_MCLepton_Eta = MCPlots.make<TH1F>("MCLep_Eta","MC_Lep_eta",100,-5,5);

 h_ele_absetaEff =(TH1F*)h_Lept_Eta->Clone("h_MCLepton_Eta");
 h_ele_absetaEff->Reset();
 h_ele_absetaEff->Divide(h_Lept_Eta,h_MCLepton_Eta,1,1);
 h_ele_absetaEff->GetXaxis()->SetTitle("|#eta|");
 h_ele_absetaEff->GetYaxis()->SetTitle("eff");

I want to write the "h_ele_absetaEff" histogram in a separate directory.

Can any one help in this issue.

Best Regards
