To manage your storage space, you may have to uninstall some other apps or games from your system.

For Steam, right-click the game in your Steam Library, select "Manage", and select "Uninstall". You can also uninstall other programs using their native uninstall wizard, or through the Control Panel.

For consoles, highlight the game or app you want to uninstall, choose "Options" , and select "Delete", "Uninstall", or "Eject from Console".
