Graphics and Flash

[No One]

I need to load either a graphic or a Flash app in my C# window app. Is
there a good way to tell what a file is other than by the file
extension?

In general, you can analyze the file contents, as both the graphic formats
and (I hope) the Flash format have their own predefined structure with
easily recognizable file header.
