Where to find the FP7 files in TS2017

[Caldrifter]

I've searched high and wide with Windows 10 search engine but I cannot find where the Steam FP7 files are. These locomotives are the only ones left that I haven't (and therefore, can't) eliminate Dan Hernandez from. Can someone give me a hint as to where they might be?

Thanks.

Make sure to open the ap. file with winRAR or 7zip.
