Notes about the MMR 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 MMR file type is primarily associated with 'LOKI' by Synthetic Realms. LOKI is a spellcrafting aid that designs equipment templates for Mythic's Dark Age of Camelot Massively Multiplayer Online Role-Playing Game.
