When you create a virtual copy of a photo, Copy 1 (or Copy 2, Copy 3, and so on) is added automatically to the Copy Name field in the Metadata panel.
In the Grid view in the Library or in the Filmstrip in any module, right-click (Windows) or Control-click (Mac OS) a photo and choose Create Virtual Copy from the context menu.
In the Grid view in the Library or in the Filmstrip in any module, Control-click (Mac OS) to select multiple photos and choose Create Virtual Copies from the context menu.
If the copy does not appear in the Grid view, the photos may be part of a collapsed stack. Try choosing Photo > Stacking > Expand All Stacks. If that doesnt work, the photos may be filtered. Try using a different display method, such as choosing All Photographs in the Catalog panel.
In the Library module, select a virtual copy of a photo in the Grid view or the Filmstrip and choose Photo > Set Copy As Master.
To delete or remove a virtual copy, expand the virtual copy stack in its folder in the Library module (press S). Then right-click (Windows) or Control-click (Mac OS) the virtual copy in the Grid view or the Filmstrip and choose Delete Photo.
