TTree::SetFolder

Hello,

I’ve created a TTree form TFolders. How can I recreate the
folder hierarchy from the tree?

The Manual says that there should exist a method TTree::SetFolder. In the 'WindowsXP, version 3.10/02 WIN32GDK ’ binary version of root this method does not exist.

Does this method exist in other root versions?
Or is there an other way to recreate the Folders?

Thanks,
Matthias
