Notes about the RCO file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
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.
