I forgot to mention the version again.

Yes, it does work for me and now I know how I should do from root/CINT shells.

What I'd like to know then is how I can change the current "drive" of TBrowsers to access files on different drives.
It seems to me that gSystem->cd() doesn't affect TSystemDirectory::workdir in TBrowser... Suppose I started root from a 'command prompt' whose current "drive" is c:. How can I access root files on d: "drive" from a TBrowser? Even after issueing gSystem->cd("d:\\"), I could only see files in the c: "drive".
(Yes, I know I can access files on d: by changing current drive to d: BEFORE STARTING ROOT.)

Yours,
Kazuyoshi
