What is a DMSE file?
Project file created by Sound Editor, an audio editing program included in the Roxio Creator multimedia suite; contains project information, including references to audio files, audio edits, and transitions; used to save and load audio projects.
NOTE: DMSE files contain references to audio files, not the audio files themselves. Therefore, if you want to share a DMSE project, you must also share all referenced audio files.
