CorsaUnlocker is a small utility for Assetto Corsa: it writes a shared collider.kn5 into every car folder under content/cars. It resolves content from the Steam uninstall entry for AppID 244210, or you can paste the path manually (UTF-8).
Important: ship the Release build of CorsaUnlocker.exe so users do not need Visual Studio debug runtimes. Build and run details are in the repo README.
