Notes about the TDMS 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 TDMS file type is primarily associated with 'LabVIEW' by National Instruments Corporation. LabVIEW is a software tool for designing test, measurement, and control systems.
