When I'm playing in version 13.20 of Factorio on Windows, I'll push F12, I get a notification that a screenshot has been saved.
However, I've looked everywhere that the screenshot could possibly have been saved and I haven't been able to find it.
Does anyone know where Factorio is saving these screenshots?
It's not a Windows notification, but a Steam notofication. Whenever you quit Factorio, Steam shows your screenshots, and asks you what you want to do with them.
Or you can go into your Steam profile, there's a "Screen captures" link on the right.
