What is a TDMS file?

TDMS files mostly belong to LabVIEW. TDMS files are Technical Data Management Stream files developed by National Instruments for use with LabVIEW.
They are binary files that store measurement data along with detailed metadata in a hierarchical structure.
  • Data Organization: These files use groups, channels, and properties to maintain a structured layout.
  • Primary Use: They efficiently record data from tests and measurements in industrial and laboratory environments.
  • Access Methods: They can be opened using LabVIEW or through specialized libraries available in programming languages like Python.
  • FilExt.com tip: For additional details, visit the National Instruments website.

    How to open TDMS files

    You need a suitable software like LabVIEW to open a TDMS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your TDMS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a TDMS file directly in the browser:. Just drag the file onto this browser window and drop it.

    Programs that open and convert TDMS files:

    1. LabVIEW
      See the previous paragraphs to learn more about the main application. TDMS files are often referred to as LabVIEW data files because this type of file is primarily created or used by this software.
    2. LabVIEW (Test Data Exchange Stream) by National Instruments Corporation
      LabVIEW is a software tool for designing test, measurement, and control systems. Related links: Wikipedia LabVIEW Page

    TDMS file extension format:

    If you can determine the file format, the associated program can also be determined. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. Exact knowledge of the format is therefore important in order to solve problems occurring in files. Our analysis of the TDMS files produces the following result:

    TDMS is rarely used as a file extension and is primarily used by a single program. The two most popular formats are as follows:

    All other TDMS files (1%) have different formats. Drag & drop your file here to see the file format and a preview of your TDMS file!

    How to solve problems with TDMS files

    • Associate the TDMS file extension with the correct application.
    • Update your software that should actually open binary data files. Because only the current version supports the latest TDMS file format. Search, therefore, e.g. on the manufacturer website after an available LabVIEW update.
    • To make sure that your TDMS file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
