Can't find Grav files

Recently I downloaded Grav onto my PC through steam of course, but if I go to my program files(x86)>Steam>Common>Steamapps, I don’t see my Grav files anywhere. But if I were to go to steam, right click the game, go to properties and go to the files from there, its there. But if I came back later, it would be gone. I even tried copying the files into a new folder and the folder dissapeared when I restarted my PC. The problem is, I can’t make any private servers because the servers can’t find the file it needs because the file isn’t there. It doesn’t show that the file is hidden so I’m not sure what I can do or what the problem is.

This is Grav the CMS, not Grav the Game, sorry wrong forum!
