Notes about the MML file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The MML file type is primarily associated with 'Aleph One' by Marathon Open Source. Aleph One is an open-source descendant of Bungie's _Marathon 2_ first-person 3D shooting game. A1 plays Marathon 2, Infinity, and 3rd-party content on a wide array of platforms, with (optional) OpenGL rendering, Internet play, Lua scripting, and more. File name extensions are usually not necessary for function of Aleph One because the antecedent source code was on the Macintosh platform.
