Notes about the PSAR 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 PSAR file type is primarily associated with 'Playstation' by Sony Corporation of America. This file is generally retrieved by unpacking an EBOOT.PBP file. It is a file archive which is compressed and tacked onto the end of an EBOOT file. It is often used in Sony's update process but it is also used for POPS format games and can be used to hold pretty much anything. The file can be used directly with the programs PSAR Dumper, Red Squirrel PSAR Dumper and DevHook; all of which require both a PC and PSP operating together to use. PSAR stands for PlayStation ARchive.
