The PlayStation 3 remains a powerhouse for emulation, preservation, and homebrew. If you are diving into the world of PS3 custom firmware (CFW) or PS3HEN, you have likely encountered and RAP files.

For unowned or delisted exclusives, the process requires a PS3 running like Evilnat or Hybrid Firmware (HFW) with HEN (Homebrew Enabler).

You have two options. Either use a tool like PS3Splitter on your PC to cut the PKG into smaller chunks that the Package Manager can automatically reassemble, or format your drive to NTFS and use the homebrew app Irisman to copy the large PKG directly to the PS3's internal hard drive ( dev_hdd0/packages ).

Before handling these files, your PlayStation 3 must be properly modified to accept unsigned or custom licenses.
