The RCO format is a resource container used by Sony PSP firmware and related system software. PSP consoles use these files for resources displayed or played by the system interface.
An .rco file may contain system information, interface sounds, icons, and other graphics used in themes. It is part of the PSP system software rather than a general-purpose document or media file.
The format is specific to the PSP platform. Existing files are mainly encountered in PSP system software and customisation work.
PSP system software loads these files automatically when they are in the appropriate system location. On a computer, an .rco file requires a specialised RCO Editor or another tool that supports the PSP resource format.
Do not edit system files without a backup, because changing an RCO file incorrectly can prevent the PSP interface from working properly.
There is no standard conversion for .rco files. An RCO Editor may be able to extract or replace individual resources and save the file in RCO format again, but this is editing or repacking rather than conversion to another format.
