Need help with downloading mods

I just got my first Windows computer about a week ago, and I just bought Beamng alpha. I have been trying to download mods, but I cant find where to drop the files. I have watched many tutorials, but it seems there is something different about my files from theirs. It says to go click "open file location" and when I do so, I just get this http://gyazo.com/686595e482b69f081237cecbf686b724

How do I get to where I can drop my mods into the vehicle folder?

Complete Windows noob, excuse my ignorance.

 

Actually you wanna go to Steam>Steamapps>common>BeamNG.drive>vehicles you should see somewhere and plop the file not the zip into the vehicles file Tell me if pics needed
