Notes about the MMI 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 MMI file type is primarily associated with 'Media Processing Server Studio' by Nortel Networks.

This product used to be known as Peristudio/PeriProducer. Extensions used by it for IVR vocabulary file manipulation include .MMI=Index, .MMD=Data, and .MMF=Reference Name.
