Cannot Install The Update File Ps4

Let’s say you’re trying to download a patch for Call of Duty: Modern Warfare and your PS4 says there’s not enough room, even though there should be. The reason you can’t download and install the update is because of the aforementioned copying procedure. When you download an update, your PS4 then makes a second copy of the game file, adds the update, installs this new version of the game, then removes the outdated version. In other words, your PS4 needs around double the storage space for a game in order to download and update it. For example, if you have 30GB free and a 2GB patch for Call of Duty: Warzone arrives, you won’t be able to download it until you make some extra room — enough to technically install Warzone twice on your hard drive. The old version will be deleted, which frees up some space again, but you need that extra space free in the first place.
