Notes about the MMX 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 MMX file type is primarily associated with 'Command & Conquer' by Westwood Studios. The epic struggle between the Global Defense Initiative (GDI) and The Brotherhood of NOD.
