A file with the DM file extension is most likely a DRM Delivery Message file. It can be any file type, but is most commonly an audio file used as a ringtone or media clip on a mobile phone. Sometimes they are also downloaded to a computer.

Since these files are protected with DRM (Digital Rights Management) copy protection software, a mobile phone must be authorized to use them.

DRM Delivery Message files can be downloaded via an installation service and have an additional file extension prepended to them, such as file.sis.dm or file.sisx.dm.
