mate, there's no standardised way of packing and distributing tracks... so you need to apply a l'il common sense when extracting them to the game... since each builder/converter does their own thing...
as mentioned, the root directory for race 07 (and all expansions) is:
C:\Program Files\Steam\steamapps\<YOUR STEAM NAME>\race 07
so, if you have a gamedata and uidata folder in the pack, then you can see they need to go there...
however, sometimes it's been packed at the locations level, so all you'll see is a folder with the track name or location, that would need to be extracted here:
C:\Program Files\Steam\steamapps\<YOUR STEAM NAME>\race 07\Gamedata\Locations
and, of course, it could be any other variant... you just need to take 2 mins to make sure you're putting in the right place.... :thumb:
