Sets the folder where files created by AGK will be stored. This has no effect on mobile platforms since they cannot write outside their app folder. Images for virtual buttons and joysticks are saved to the original write path, so when you try and create a virtual button or joystick the first time it looks for the image. If you have changed the path between starting the program and creating the first button or joystick then this will fail, creating the button or joystick first and then changing the path will work as once the image is loaded it stays loaded even if all buttons or joysticks are deleted.
