i am gonna say it very very specificly so you can get right. Go to "my computer" on your menu, then look for a folder that says program files. Scroll down untill you find your steam folder, then go to steam apps. Click on your steam user name, then race 07, then you will find the gamedata folder and uidata folder. Some cases you will extract the track inside the race 07 folder (where the gamedata and uidata is at), but most of the time you will go into the gamedata folder and go into the locations folder and extract it there. The way you can find out where to put the track is to put it in either way. If you put it in your race 07 folder and it has a folder for the track after you extracted it there, then that means you put it in the locations folder. If you put it in the locations folder and makes a folder for gamedata and uidata, then you put it in the race 07 folder. Hope that helped you get going.
