Okay, when you do that the copied icons files is deleted. So that copied files no longer exist on the desktop. The original files is still there. But if you restore layout. Fences will look for the copied files to restore into that Fence.
Remember, "Fences helps you organize your PC by automatically placing your shortcuts and icons into resizable shaded areas on your desktop called fences."
Fences will not recreate shortcuts/program etc.
Thank you,
