Notes about the DDR 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 DDR file type is primarily associated with 'DDRemote' by Microcosm Ltd.. Dinkey Dongle prevents illegal copying of your software by locking it to a hardware key (dongle) that plugs into the parallel printer port or USB port of a computer. The DDR file contains parameters for the DDRemote program that generates code to modify dongle parameters.
