.cmf File Extension

Developer: Creative Labs
File type: Music File
You're here because you have a file that has a file extension ending in .cmf. Files with the file extension .cmf can only be launched by certain applications. It's possible that .cmf files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .cmf file?

The CMF file extension is a data format associated to Creative software. CMF files and Creative software were developed by Creative Labs. These files are audio files that contain music data in the form of notes and instruments that are used for playing back different sounds in synthesized MIDI format. They are designed to be used by Creative Sound Blaster sound cards and Creative software. They are also known as Creative music files. Technically, they contain three blocks of data, which include the header block, the instrument block and the music block. They were popularly used for computer games like Kiloblaster and Jill of the Jungle. They are similar to MIDI format, but unlike MIDI, they allow custom synthesized instruments to be stored in the file itself. Synthesized instruments were produced using the Adlib/SoundBlaster OPL chips. Files in CMF format can be opened with Nullsoft Winamp Media Player 5.6 with AdPlug plugin in Microsoft Windows based systems. In Linux, they can be opened with XMMS with AdPlug plugin.

a word of warning

Be careful not to rename the extension on .cmf files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .cmf. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
