Notes about the 00N 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 00N file type is primarily associated with 'Portable Navigator' by ESL Software. Portable Navigator is a Navigation Plotter intended for users who want to be able to make their own charts and maps, and who are interested in logging masses of data in formats that they can define, and who want to interface various NMEA measuring instruments to their on-board system.
