On the VFS system, do they show in Explorer?

[AndyXheli]

Yes works on Explorer

I can also confirm this issue with the tray window.
Probably unrelated: on the VFS system, the shell integration with windows explorer basically works, but also has issues in some multiuser conditions as described in #5301.
