DR File

Files with the DR extension belong to the category of text files. They contain data used in DRM technology. These resources are found alongside DRM objects and DRC. DR files store sets of permissions, written using XML syntax, and the key encrypting the content of DCF files. Files with the DR extension are in text format.

How are DR files used?

DR files enable the editing of selected resources exclusively on a single, defined device. The DRM technology, which relies on DR files, is therefore used to protect software and electronic content against unauthorized access. In practice, it is possible to freely download files protected by DRM, as well as copy them between multiple devices. However, to open such protected objects, a dedicated DR file must be present on the specific device. It defines the user's rights to handle protected resources, and contains the decrypting key of their content. Without the appropriate DR file, editing objects secured by DRM technology is impossible.
