Notes about the NV3 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 NV3 file type is primarily associated with 'Visicontrol MVS-30/35/40 Flash-Memory Backup File'. (Ver 3.0+)
