How to show desktop files on both screens? I have a dual monitor setup. Files in the desktop are shown on the first screen. Is there a way to have those files also appear (mirrored) on the second screen?

I do not want screen mirroring, I just want to mirror desktop files. Is that possible?
I'd like to do the same thing, but I haven't found a way. The best compromise I could come up with was to move the menu bar to my primary display. By moving the menu bar, I changed the display which shows my dock and desktop files.

You can move the menu bar by dragging white bar in the Arrangement settings from one display to another:
