Dear Rooters,

This must be an known question. But I have not been to it yet

I wanted to open a tree file file.root which is converted by h2root. This 
file is written by other users. I  want to inspect the content of this 
file using TFile f("file.root"), then f.ls(), but I dont see the object 
name of the Tree. I only see something like this:

TFile**         run005.000001.root       HBOOK file: run005.000001.hbk converted to ROOT
 TFile*         run005.000001.root       HBOOK file: run005.000001.hbk converted to ROOT

I tried f.ReadKeys(), but does solve it.
I wanted to write a class using the 
Object_Tree_I_am_Looking->MakeClass("Name"), so I need to know the object 
name.

How do we proceed openning this file?

Thank you.
