What is a COPY file? A COPY file is an encrypted audio file that originated from a Sony Ericsson mobile phone. It contains a song or other audio that has been protected using Sony Ericsson's Digital Rights Management ( DRM ) system.

More Information DRM systems allow publishers who provide electronic media to users to limit how users can use those files. For example, publishers often use DRM systems to prevent users from sharing copyrighted material with others. Sony Ericsson mobile phones use a proprietary DRM system to limit users' ability to share protected audio content. Audio files protected using this system are saved as COPY files. NOTE: Previously, Sony Ericsson DRM Packager could be used to convert an unprotected audio file into a COPY file. However, the program is no longer available for download.
