Nautilus question

[GR Gaudreau]

Hi all,
I installed Ubuntu Linux 4.10 for the first time yesterday -- beautiful,
I love it!

I'm not used to how Ubuntu works -- I was a Mandrake Linux fan -- so I'd
like to know how to browse files with Nautilus without having to open
several MacIntosh-style windows, but have a "Windows Explorer" type of
arengement; where the left pane is a tree view and the right pane is the
file view. How do I do this from the first Nautilus window you open?
Thanks.

Cheers,
GR
