Notes about the NX1 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 NX1 file type is primarily associated with 'NexusDB' by Nexus Database Systems. NexusDB is a commercially available SQL:2003 databases for the developer market. This is an older format file; NX2 is the more current format.
