Because of Sony’s encryption, you cannot just download a .zip file from a forum and copy it to your PS4. You will get an error: "Cannot copy. Saved data belongs to another player." How to Bypass the Protection (Advanced Users Only) To use a downloaded save file from the internet, you need a Save Resigner or a Save Wizard (paid third-party software).

Format a USB drive as exFAT on your PC. Create a folder called PS4 , then inside that SAVEDATA , then inside that a folder with your User ID number (you find this via Apollo tool or by looking at your own exported save structure).
