Note that you may need to 'show hidden files and folders' under Explorer's setting first, to do so under something like Win7, as 'Application Data' is otherwise visually hidden from you.
Unfortunate folder pathing choice there by the sins devs. The better, more visible place would have been under the user's "My Documents/My Games/such-and-such", which is where things like Civ4 and Bioware and so forth naturally reside. It's just a lot easier to see and manage, as turning on show all shows desktop .ini files and all sorts of things globally.
Anyway, just a remark for the small subset of Win7 users who might encounter small confusion.
