Notes about the P3T 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 P3T file type is primarily associated with 'Playstation' by Sony Corporation of America. Theme files customize the visual experience on the Playstation. They may contain various icons (GIM files) as well as the basic theme graphics.
