( on my Win7 System )
I went to Control Panel -> Network and Sharing Center -> Advanced sharing settings
Under network discovery made sure ‘* Turn on network discovery’ was selected.
(for some reason it was greyed out until I rebooted)
Opening Explorer only shows the VolumioXX device by name and gives properties when double-clicked.
But, when I typed “\VolumioXX” on the command line I was able to see an Internal Folder, USB folder, and NAS folder.
Only the USB folder had an item which was the volume name of the pen drive inserted on the Volumio device.
