PlayStation 4 storage is a lot like your computer’s hard drive. It can be used for games, pictures, music, and videos. You can also create folders to organize these things. There are three types of folders on a PlayStation 4: system files, user files, and game data. System files are the files that are stored in the root of your PlayStation 4 hard drive. These include the game’s executable file, the application data folder, and any other files that may be needed to run your game. User files are the files that you create yourself. These include documents such as user manuals and software applications. You can also create folders for these documents so that they are organized according to type of document (e.g., manual folder for software applications). Game data is the final type of folder on a PlayStation 4 hard drive. This is where you store all of your game saves and progress information.
