When you've done that, set up a mods folder. and all your game files will get put back to their default state. Steam will verify the game's files and restore them to the originals Go to your Steam Library, right-click on the Grand Theft Auto V entry, choose Properties > Local Files > Verify Integrity of Game Files.
Select the Local files tab and click the Verify integrity of game files button.
