1. Go to your Steam installation folder.
   
   The defaut path is: "C:\Program Files (x86)\Steam"
2. Open "userdata".
   
   
3. Then open the folder with your SteamID3. (Examble: "32524734")
   
   (There might be a few other folders named with Steam ID there if you are using multiple Steam accounts. If you use one account only, there will be only one folder. You can find the ID for your main account HERE[steamid.io]. The name of the folder you are searching is "steamID3".)
4. Open the "730" folder.
   
   
5. Open the "local" folder.
   
   
6. Open the "cfg" folder.

8. Done.

If you want to ZIP the files then follow the following steps with the files you backed up:
