What are CCM files and how to open them

What is a CCM file?

A .CCM file is a Creative Commons Module Music file.

Creative Commons Module Music files bundle musical projects created under a Creative Commons license, storing composition data and associated resources in a compressed archive. Designed for remixing and sharing, these files integrate multiple elements of a composition so collaborators or playback tools can access both the track layout (such as what instruments play when) and the resources those tracks use, like samples or submodules.

These files are written by the Creative Commons Module project. They are not simply audio recordings; they contain editable music data including manifest information, structural song descriptions, instrument definitions, and possibly custom submodules. The project's goal is to enable modular, shareable music projects that preserve the components needed for modification or remixing, rather than just output as a mixed audio track.

Technical identifiers for this format include a ZIP-compatible header beginning with the bytes PK 0x03 0x04 at offset 0. The archive contains key files such as manifest.xml, song.xmix, and entries like .cpp and .hp files, along with signatures like "TRAC.ZEITHERRSCHAFT.ORG."
