.COPY File Extension

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.

No known program can open COPY files. If you have a Sony Ericsson mobile phone, you may be able to open your COPY file on that device.
