You don't need a massive external hard drive to move 50GB+ games. Batch Installation:
An is not an official Sony tool. Instead, it is a custom homebrew application typically run on a PS4 with specific firmware versions (usually 9.00 or lower). Its primary function is to automate the process of detecting and installing PKG files from a USB drive or network server without needing to navigate complex menus or use manual commands. auto package installer ps4
The API leverages the PS4’s internal pkg_install function, the same system call Sony’s debug OS uses. However, it wraps this with a recursive file scanner. You don't need a massive external hard drive
This is preferred for users with a laptop and no large USB drive. Its primary function is to automate the process
Not all PKG files are created equal. A dump from a scratched disc or an incomplete backport may crash your game or, worse, corrupt your save data. Auto installers do not verify the integrity of the PKG before installation—they assume the file is perfect.

The result is a , meaning that specific PS4 can never connect to PSN again. Online multiplayer, cloud saves, and store access are gone forever.
This is a common "stall" due to a corrupted PKG or an incompatible backport. The auto installer will try to install it, fail, and hang because it cannot skip the file. Solution: Remove the problematic PKG from the USB and run the installer again.
