What is a THD file?

THD files mostly belong to MediaInfo. A THD file can contain data from very different sources. The most common use is for storing Dolby Digital TrueHD audio data. This format carries high quality, lossless audio used in advanced playback systems.
Other uses include:

Test History Data: A THD file may record test results from tools like the Ellisys Bluetooth Protocol Analyzer. This data is viewed with specialized analysis software.

Messenger Thread: Some files store chat history from Facebook Messenger. In this case, the file holds conversation data.

TimeHarp 200 Data: In scientific setups, a THD file can keep measurement data captured by TimeHarp 200 devices, used in time-correlated studies.

FilExt.com tips: Identifying the file source is key to choosing the correct application for opening or viewing it. For audio files, tools such as MediaInfo or plugins for players like foobar2000 are often used. Each use case has its own set of compatible software, including products from Ellisys, Facebook Messenger, or PicoQuant.

How do you open THD files?

THD file format:

A file format defines how the data in the file is structured. 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. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. So you need a detailed analysis of a file to find out the format and the associated program. Our analysis of the THD files produces the following result:
