Recent update to Windows 10 means I’ve lost Microsoft MovieMaker, and have to use the Photo app for editing my, erm, edits now.

I’ve added a handful of mp4 files to the project, trimmed them and duplicated them so I’ve got about 25 clips I want to work with, but I’d like to copy the Project before further editing to keep options open so I can try different things, but always from the same startpoint.

Any idea how to copy a Project? It was easy in Moviemaker, but it doesn’t seem obvious now.
