Technical Data Management Streaming (TDMS) is a file format based on the National Instruments TDM data model used to stream data to disk. You can use the TDMS .NET class library to describe, store, and read measurement data that is optimized for high-speed data streaming and post processing. Files created with the TDMS .NET Library can be used in LabVIEW, CVI, and DIAdem, and files created by these applications can be used by the TDMS .NET Library.

Refer to Using the Measurement Studio TDMS .NET Library, Key Measurement Studio TDMS .NET Library Features, or Creating Measurement Studio Projects for more information. You can find sample applications in the Tdms Example folder.
