How to open TDT file?

An often recurring problem with THOR Data Tree Format is that TDT is not associated with the correct program file. Thus, when you open TDT, the program selection wizard or some other program starts. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the TDT file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install THOR-Merlin System

The first step is to check if the computer has the THOR-Merlin System program installed. To do this, enter the name THOR-Merlin System into the system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file TDT.

Programs to open TDT file

Remember to download programs supporting TDT files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of THOR-Merlin System with TDT files

If, despite the installed application, the TDT file does not start in the THOR-Merlin System application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can set the program to handle this type. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. Checking the "Always use the selected program ..." box will permanently associate the TDT file with the THOR-Merlin System program.

Step 3. Update THOR-Merlin System to the latest version

The fault may also lie with the THOR-Merlin System program, it is possible that THOR Data Tree Format requires a newer version of the program.

Step 4. Check for the following problems with the TDT file

Of course, it may happen that despite the above steps, the file still does not work. File problems can be divided into the following:

The affected file may be 0 KB or smaller than expected. This suggests truncating the TDT file contents when downloading or copying. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file TDT or the program directory. However, remember that not every infected TDT file can be recovered, so it is important to take care of regular backups.
Older version of TDT file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular TDT file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted file TDT except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. These directories are write-protected to them and it's very hard to fix this problem. It is best to move TDT to a different directory.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the TDT file again. However, some background programs may block the TDT file while scanning. If this does not work either, restart the device.
