Opus displays only the physical drives on my computer.
I am unable to show the shared networked drives.
(They show very well however in Windows Explorer).
Please advise what I can do to have Opus display all my networked drives (also their names on the tool bar)
Where are you looking?
If you're only talking about the toolbar then your toolbar's drive-buttons are probably filtering drives by type, e.g. only showing fixed local drives (HDDs and SSDs).
Go to Settings -> Customize Toolbars, then right-click the drive buttons (which will have turned into one or more placeholders) and edit them to see which commands they are currently running. e.g. Go DRIVEBUTTONS=fixed would not show network drives.
