Where is control scheme stored?

[alphaniner]

I customized my control scheme heavily. I'm about to clean my install for an overhaul mod and want to avoid losing the customization. I don't see anything related to controls in the AppData folder, or under the registry key mentioned therein.

 

Edit: Elsewhere someone pointed out that profiles.sdf is the most likely candidate. But the file modification date isn't affected when a change is made to the scheme, which suggests otherwise. I suppose it's possible certain operations can modify a file without changing the modification date though, so I'm looking for a program to browse that kind of database.

 

Also curious to know if the customization will carry over to A18.
