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.
