Saving configuration?

[DEATHLOK]

I thought I had all my bases covered before formatting my hard drive....

Just re-installed Windows 7, forgetting to backup my Warframe configurations. So, just in case this ever happens again, which files do we need to copy to preserve keyboard, video, audio, interface, and other important settings?

I believe this should be it, enter

%localappdata%

into the Windows Explorer address bar / the search field in your Start menu
then find the Warframe folder, in which there should be your Profile folder (the one with random letters and numbers),
containing your settings file, copy that file somewhere safe and later paste it over the one created by your new install.

[No guarantees though, make backups of everything if possible.]
