If you have deleted data on your PlayStation 4, there are a few things you can do to recover it. First, try to find the game or application that you deleted the data from and look for a backup or restore option. If that doesn’t work, you can try to format your PlayStation 4 and then back up your files using the PlayStation 4’s built-in software. Finally, if all of these methods don’t work, you can contact Sony customer service and ask them for help.
