Dear Valeriy Thank you for your answer. I am not sure if I understand it correctly: Do you mean to place 100 000 TObjects in TFile? What I did at the moment is to create a system directory with 10,000 empty text-files in it. It took TRootBrowser 115 seconds to open this directory, which is much too slow to be useful. Do you mean that grouped items are hidden from the browser because of this slowness? Do you have some simple example?
