John, OP,

Yes, I was going to suggest DIR as well. But I think he wants
only the tree, not the files.

You mean like you get with "DIR /ad /s /b" ?

If it would be me I would suggest the OP to use exactly that, instead of
that graphical tree representation.

Being able to just copy-and-paste a certain line from such a file into the
filebrowser to get at a certain directory (read: not having to traverse the
graphical tree while doing the same in the filebrowser, which is prone to
mistakes) is a big pre for me.

Regards,
