Deleting Everything
Data in your console is organized in many different ways. The PS4, for example, has folders and like a computer, you don’t just go deleting whatever folder you want to make space. The reasoning for this is simple – some folders could contain DLC content, save files etc. While it’s a matter of just re-downloading, it can still be a pain to retrieve all of the missing content and saves (the latter especially if you don’t have PlayStation Plus and cloud save storage).
