Thank you for the response. The first thing is the names of my 2 WD NAS drives were showing in the directory tree, then I suspect a recent WIndows update changed something. The devices are showing as icons in the main right hand area of the screen when the tree is on the left.
I tried right clicking on them to mount public share and nothing happens.
Yes it is Windows 10 and I have WD discovery and WD Smartware on the machine.
