Notes about the ODA 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 ODA file type is primarily associated with 'AIBO' by Sony. The file AUDIO.ODA is the voice file for the AIBO ERS-7 robotic pet. Voice files and other AIBO hacks can be found at the AIBOHack site (among others).
