The first thing you should do is just "doubleclick" on the CQT 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 Mail.Dat

Programs to open CQT file
Remember to download programs supporting CQT files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of Mail.Dat with CQT files
However, it may happen that the application itself does not cause the CQT file to open in the Mail.Dat application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the CQT file with the Mail.Dat application.
Step 3. Update Mail.Dat to the latest version
The fault may also lie with the Mail.Dat program, it is possible that MAIL.DAT Container Quantity Data requires a newer version of the program.
Step 4. Check for the following problems with the CQT file
If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:
The affected file may be 0 KB or smaller than expected. This suggests truncating the CQT 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 quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our CQT file. However, remember that not every infected CQT file can be recovered, so it is important to take care of regular backups.
Older version of CQT file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged CQT files.
The program can also signal the fact of encryption. The encrypted CQT files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
Some of the system directories are excluded from modification. While there is usually no problem reading such a file, it may not be possible to save it. Copying the CQT file to another location will fix the problem.
This problem only occurs with more complex files. Some file types can only be opened in one program at a time. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file CQT to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
