Probably. Who knows about flight sim programs? Can you download different airports and then fly repeated simulations? Then delete the simulation flight and save the airport?
A lot of programs will have a listing of recently accessed files. Not uncommon for someone to work up drafts, clear the list of all the drafts, then be able to go between final products more quickly. In this context, take that how you may...but it’s a fairly normal workflow for working on audio or images.
