What is a .DM file extension?

.DM file extension is created by Sony Ericsson. .DM has been classified as Audio Files.

.DM is DRM Delivery Message

File (often audio) that has been encoded with DRM (Digital Rights Management) copy-protection; used by some cell phones for ringtones and other media clips, but can also be used for digitally signed mobile applications; can only be opened using an authorized cell phone.

Normally DM files are installed in the background using a mobile phone download and installation service such as the online Nokia Ovi Store. However, sometimes users download DM files manually and save them to the desktop. For example, a user could save a Nokia Ovi Store .SIS or .SISX application file as a .SIS.DM or .SISX.DM file.

DM files can also be created with the DRM Packager Tool for Sony Ericsson phones.
