.GP5 ファイル拡張子

A GP5 file is a project file created by Sony's PlayStation 5 software development kit (SDK). It contains data used to package a PlayStation 5 (PS5) game development project into a .PKG file. Developers create GP5 files with GP5 Generator for PS5, also known as GP5 Editor.

To create games for the PlayStation 5, developers must apply for and receive a copy of the official PS5 SDK. This kit contains several proprietary development, publishing, and testing tools, including GP5 Generator for PS5.

Using GP5 Generator, a developer can create a GP5 file for a game development project. This file contains a record of all the files included in the project and those files' locations. When the developer uses the PS5 SDK to create a finalized game package, they must specify their project's GP5 file. The SDK's Package Generator uses this file to build the resulting game package.

注: At times, developers refer to GP5 Editor as Prospero GP5 Editor. This is because the PS5's pre-release codename was Prospero.

GP5 files are not meant to be opened. Developers who have access to Sony's PlayStation 5 SDK can use the kit's Package Generator to load GP5 files and create resulting PKG files.
