Notes about the FPI file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The FPI file type is primarily associated with 'FPS Creator' by The Game Creators Ltd.. FPS Creator is a game creation program with an easy-to-use yet highly flexible editing environment. As its name implies (FPS = First Person Shooter) this is a tool for creating action FPS games with no programming or 3D modeling knowledge required. The compiled game will be a standalone EXE file.
