Ps4 not enough free space?

I have a PS4 with 500GB storage space. Of that, 113.6GB are free according to my PS4. The problem is that I want to download an update for a game. If I want to download it I'm told that not enough free space is available. Can somebody help me?

Delete unnecessary files, such as Videos in the gallery or even games that you no longer play.

But if you're a hardcore gamer, I recommend buying an external hard drive.

As a guide: The PS4 requires an update once again the full size of the game as free space.

By reinstalling one bypasses this.

Hardcore gamers do not buy any external. If then an internal and as a hardcore gamer please a big SSD.
