it saves in the tiny tuner folder under logs iirc. theres a set up button top left iirc, click that and you will see a part where you open note pad and change the path if you want to save it to your own folder.
they are named racetrack and the date when you save it. "Racetrack01-09-17" or something like that.
and i pretty much use dhp only for my scans, tt is a bit clitchy to me when scanning. not sure if its my lap top or what.
edit: not tiny tuner but the UV scan folder, ah durrr.
