Folder Tree Header with drive letter

Is there a way to show the current drive letter on the folder tree header?

Or if not, can you suggest a quick way for me to see the drive letter of the current folder I have selected?

Also, is there a setting to un-expand (collapse) a folder when I select another? Many thanks.


You could adapt the Lister title bar

This might help

Thanks for the lister title bar tip. On the other, I thought that setting would collapse non-selected folders but it doesn't seem to work for me.
