I just created a virtual copy of a photo and it seems to have disappeared. The folder says that both of the photos are in the folder. But they don't show up. Where can I find them?

I can’t find an original photo and the virtual duplicate that I created. After I clicked on “Create Virtual Copy” both the original and the virtual copy have disappeared. But the number of images in the folder indicate that they are both in there. I can’t see them. Where would I find them?
