How to open MTT file?

The most common problem when using Microsoft Messenger Saved Contact Format is that a specific MTT is not associated with the program. This is manifested by the fact that MTT files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the MTT 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 Windows Live Messenger

The first step is to check if the computer has the Windows Live Messenger program installed. To do this, enter the name Windows Live Messenger into the system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open MTT files.

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

Step 2. Create association of Windows Live Messenger with MTT files

If, despite the installed application, the MTT file does not start in the Windows Live Messenger application, you must create a file association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can set the program to handle this type. 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. Checking the "Always use the selected program ..." box will permanently associate the MTT file with the Windows Live Messenger program.

Step 3. Update Windows Live Messenger to the latest version

If, however, after binding Windows Live Messenger with Microsoft Messenger Saved Contact Format there were still problems, you should update the program to the latest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Microsoft Corporation page and install.

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

If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the MTT file. 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. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our MTT file. Sometimes virus-infected MTT files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the MTT files changes over time. 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.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged MTT files. The easiest way to restore the file is from a backup or by contacting Microsoft, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted MTT files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the MTT file to another location.
This problem usually affects more complex files. In this case, the MTT file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the MTT file again. However, some background programs may block the MTT file while scanning. If this does not work either, restart the device.
