MCI file extension - Media Control Interface command script

What is mci file? How to open mci files?

File type specification:

System file type icon System file type

mci file icon: mci filetype icon

The Media Control Interface, the mci file extension is an aging high-level API developed by Microsoft and IBM for controlling multimedia peripherals connected to a Microsoft Windows or OS/2 computer, such as CD-ROM players and audio controllers.

MCI makes it very simple to write a program which can play a wide variety of media files and even to record sound by just passing commands as strings. It uses relations described in Windows registries or in the [MCI] section of the file SYSTEM.INI. One advantage of this API is that MCI commands can be transmitted both from the programming language and from the scripting language (open script, lingo aso).
