.MSC File Extension

File added to the Microsoft Management Console (MMC), a program used to configure and monitor Windows computer systems; contains a "snap-in," which is a module that provides additional administration capabilities.

Snap-ins are commonly used by system administrators for device management, disk defragmentation, and system event monitoring. Custom snap-ins can be developed with the MMC Application Programming Interface (API), which is published by the Microsoft Developer Network (MSDN).

NOTE: MMC is included with Windows operating systems beginning with Windows 2000.

File created by MuseScore, a free program used for music composition and notation; contains the composition, which includes the key signature, instruments, time signature, and music notes; also contains score metadata, including title, subtitle, composer, and copyright information.

MSC files are used by composers to store musical scores. They can be translated into twenty different languages in MuseScore.

NOTE: MSC files apply to MuseScore versions 0.9.4 and earlier. MuseScore version 0.9.5 and later use the .MSCX file extension.
