Movie project created with VideoWave, a video editing program bundled with Roxio Creator; contains movie project data and settings, including effects, transitions, references to video and audio files, and other video editing information.

DMSM files are used to save and load project information for video editing. They can be exported to a variety of video file formats or burned to DVDs and Blu-ray discs for sharing with others. NOTE: DMSM files are not suitable for sharing with other users since they contain references to video and audio files, but not the files themselves. If you want to share a DMSM project for someone else to edit, you must also share all referenced multimedia files, which must be organized using the same directory structure.
