Notes about the DR file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The DR file type is primarily associated with 'Open Digital Rights Language' by ODRL International Advisory Board. The Open Digital Rights Language (ODRL) Initiative is an international effort aimed at developing and promoting an open standard for rights expressions.
