What is a .TDX file?

The .TDX file extension is used for a specific type of file called a D-TEG CCTV Video Information File. This kind of file is created by security cameras that are part of a closed-circuit television system, also known as CCTV. These systems use digital video recorders, or DVRs, to save video footage. The .TDX file contains important information that helps manage and play the video recordings made by these DVRs. For a video to play back correctly, the .TDX file needs to be kept together with the actual video file it is associated with. This means if you have a video from a D-TEG CCTV system, you need to make sure the .TDX file that came with it is not deleted or moved to a different location; otherwise, you might not be able to watch the video.

To open a .TDX file, you need to use a specific program called D-TEG MRX PC Client. This program is usually provided with the D-TEG DVR system. It's designed to work with these files and allows you to view the video recordings on a computer. Without this program, it's not possible to access or view the content of .TDX files because they are made to work only with the D-TEG system's software.
