I deleted every folder to uninstall steam including steamapps I installed steam again and my games are gone can I get them back or no?
All games that are purchased through steam are stored in your steam library. If you log into the program using your username and password (after reinstalling steam) all of your games will be available for download there!
If you are sure that you are logged into the correct account, and don't have "installed" selected in your library (thanks @DJPirtu), try reinstalling steam. If this still doesn't work contact steam support.
