Notes about the RCO 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 RCO file type is primarily associated with 'Playstation' by Sony Corporation of America. PSP is a portable Playstation handheld entertainment system. This file type is found in the firmware but can be changed. Search for RCO Icon Editor or other like programs. Be careful; modifying the firmware can render the PSP useless if done incorrectly. The PSP's flash contains numerous RCO files (localized resources)
in the flash0:/vsh/resource folder.
