All about WDH Files

The WDH file type is primarily associated with LabVIEW.

WDH	File extension: WDH
	File type:	waveform data file

What is a WDH file?

WDH files mostly belong to LabVIEW.

This Waveform Data File (WDH) stores measurement signals in a format tailored for data acquisition systems. It is used chiefly in environments that deploy LabVIEW for recording and later analyzing waveform data.
Key details sourced by FilExt.com include:

Data Storage: The file holds arrays of numerical values alongside metadata that describes the waveform.
Usage Context: It is primarily used within LabVIEW and is also known in similar setups as a DIAdem Data File.
Performance: The structure is optimized for high-speed data logging and efficient retrieval.

FilExt.com note: You can open these files using LabVIEW or DIAdem software. For technical details and support, visit the National Instruments website.

How to open a WDH file

You need a suitable software like LabVIEW to open a WDH 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 WDH file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a WDH file directly in the browser:. Just drag the file onto this browser window and drop it.

How to solve problems with WDH files

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