Windows offers 2 Desktop:
(1) Current user: C:\Users\<username>\Desktop
(2) All users: C:\Users\Public\Desktop

XY offers 3 Desktop:
(1) Current user: #553 or goto "%UserProfile%\Desktop"
(2) All users: #560 or goto "%PUBLIC%\Desktop"
(3) Virtual Desktop: #590

So, my question is:
A) What is the purpose of Virtual Desktop? It seems equivalent to (1) but not showing any item in (2).
B) Is there any way to browse both (1) and (2) silmutaneously. I mean real-time, not using QNS or Paper?

A) Virtual Desktop is the equivalent of entering just 'Desktop' (goto 'Desktop';).
It's technically different from the other two but typically maps to one of them.
In other words, it's a fun crazy Microsoftian technical thing.

B) Not in the same tab.
Depending on tasks your best option is either QNS or dual pane with sync browse.
