On the PS3, digital games, DLC, and applications are distributed as PKG files, which act like compressed installation packages. Contains the actual game data.

Place your .rap files inside this exdata folder.

This guide explores how PKG licenses work, why they are necessary, and how to manage them on modified consoles (CFW/HEN) or emulators. What are PKG Licenses?

Connect the USB to the right-most port of your PS3 and enable HEN or your CFW . Some tools will activate the license "on-the-fly" the first time you boot the game with the USB inserted. Method 2: Internal HDD Storage

The PlayStation 3 (PS3) ecosystem uses a digital distribution system where software is packaged into files. However, installing a PKG file is only half the battle; to actually run the content, the console requires a valid license , typically in the form of a .rap file.

For a more permanent solution, you can move the RAP files directly onto the console's internal hard drive.
