What is an MMI file?

MMI files mostly belong to Email client, MikuMikuDance, minimap2, OziExplorer. An MMI file can be one of several data formats. It may hold an Outlook email message that stores email content, which you can open with an appropriate email client.
It is also used as a Music Macro Language file containing text instructions for music synthesis, often supported by software like MikuMikuDance.
Some MMI files serve as a microscope image file or even a raw MIDI sample dump used with diagnostic tools such as Qualcomm's QPST.
Other uses include a reference index for the minimap2 tool, a file that speeds up genomic sequence mapping; more details are available on the minimap2 webpage.
There are also MMI files that use an XML format to store structured data for applications like ManageSoft Usage Meter or Modular Modeling Interface.
In addition, some MMI files are formatted as a GPS map file used by software such as OziExplorer; further information can be found on the OziExplorer webpage.

MMI format details:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). File extension, signature and file format must match; otherwise errors will occur when the file is opened. When there is a problem with a file, the first step to solving it is to determine the file format. Our evaluation of the MMI files looks like this:

The MMI file extension is rather rarely used and is used by a few programs, each with its own file format. But the following two file formats are common:

40% of all MMI files start with the magic bytes From: , which are always the first bytes of this file format. The file size is in the range of 2 KB to 460 KB. The file type was primarily used more than 10 years ago. The keywords From, Subject, Date, IKEA3 and MIME are typical for these files. Files like these have the following tags: ikea and pollution.
7% of all MMI files use the same file format, which can be identified by the letters "[mml-score] version=1 title= author= time=" at the beginning. The contents of these files can even be read by a human. The file size is in the range of 3 KB to 12 KB. The following keywords are characteristic: [mml-score], author=, mml-track, title=, version=1, time=4/4 and tempo.

All the rest of the MMI files (53%) have different formats, often e.g. XML, FISM and MMI. Sometimes used for gwrs, gregorys, tour, collection, computer, famous, cape, info or rave. If you want to find out what your MMI file contains, drag and drop it onto this page.
