TGFileDialog drive hopping on Windows

under UNIX based operating system in which every file is accessible from a common directory tree, the ROOT file picker works well.
However, under Windows, each drive (A:, C:, etc…) spawns its own directory tree. Is there a way to hop from drive to drive ?

Thanks for your help.

You can install ROOT with Qt layer and use QFileDialog class instead
The class uses the local system facility if available. Under Windows one will have everything including drives, network devices etc.
See ROOT manual page 428

Thanks, I should have thought of your handy QT layer.
