Notes about the MZC 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 MZC file type is primarily associated with 'MOZART' by David Webber. Mozart is music notation software that allows you to type in music notation - as easily as entering text in a word processor - view it on the screen, hear it, edit it, and then print high quality music scores and individual parts for musicians.
