PKG (short for "Package") is the standard installation file format for PlayStation software. When you download a digital game from the PlayStation Store, the PS4 downloads a series of encrypted PKG files. Legitimately, these files are used for:
However, in the modding scene, "PKG PS4 games" usually refers to Fake PKG (FPKG) files. These are decrypted, modified, or repacked versions of official PKG files designed to run on jailbroken PS4 consoles (firmware 9.00 or lower, as of this writing). Fake PKGs remove the encryption tied to your specific PSN account, allowing installation on any compatible jailbroken system.

Think of a PKG file like a .zip or .rar archive on your computer, but specifically designed for the PlayStation ecosystem. It is a container format used by Sony to package digital content.
When you buy a game from the PlayStation Store, the console downloads a PKG file, unpacks it, and installs it onto your hard drive. Inside a PKG, you’ll typically find: | Type | Description | |------|-------------| | Base
For the homebrew community, PKG files are the standard format for installing custom software, game mods, and backup games.
This is the best method for smaller files or if you don't want to set up a network connection.
