Notes about the XPD 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 XPD file type is primarily associated with 'Playstation' by Sony Corporation of America. These are usually small ASCII files with instructions and pointers to other files such as PBP firmware updates. They are often used for digital rights management and are used by the Playstation Network Downloader when downloading from the Playstation Store.
