What is a PUP file?
A PUP file is a file or patch used to update the PlayStation 3 (PS3) system software. It may include security patches, bug fixes, and extra operating system features. PUP files are typically named PS3UPDAT.PUP.
You can choose to update the PS3 console by downloading the PUP file from the Internet directly to the console. You can also download the PUP file from the Internet to your computer, then transfer the update file using storage media, such as a hard disk or USB storage device.
When transferring the PUP file from a storage device to the PS3, save it in the /PS3/UPDATE folder. To update the PS3, select in the console, then press the "X" button on the controller to begin the update process.
NOTE: To extract the contents of a PUP file in Windows, use the PS3 PUP Extractor program.
