How can I access video settings via files?

there are a-lot of settings in the registry, not just the files, use the 7dtd launcher, go-to the tools tab, and use the shortcut in there to view the settings.
just be very very careful if you decide to change anything there.
however, im not sure you can do what you ask, though it should definately be fixed if you cannot, accessibility is a very very important thing, and there's really not an excuse to not have the basics covered.
