How to open MMT file?

The main problem with CoCo Systems VisiMap is that the MMT file is incorrectly associated with programs. Thus, when you open MMT, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the MMT 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 VisiMap Professional

Programs to open MMT file

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

Step 2. Create association of VisiMap Professional with MMT files

However, it may happen that the application itself does not cause the MMT file to open in the VisiMap Professional application, but you can set it manually. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. 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. The "always use the selected program ..." field will set the VisiMap Professional application as the default for handling the MMT file.

Step 3. Update VisiMap Professional to the latest version

If, despite the association of the VisiMap Professional program with the CoCo Systems VisiMap file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the CoCo Systems Ltd. website or update the program from the application.

Step 4. Check for the following problems with the MMT 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:

Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the MMT file. The only repair option is to download the file again.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. For the best results, we will scan the entire operating system, not just our MMT file. However, remember that not every infected MMT file can be recovered, so it is important to take care of regular backups.
This can happen especially when the program is dynamically developed and the structure of the MMT files changes over time. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged MMT files. You can restore the file from a backup or use CoCo Systems Ltd. help.
The program indicates that the file is encrypted or corrupted. The encrypted file MMT 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.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the MMT file to another location.
This problem only occurs with more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the MMT file for a certain period of time. If nothing helps, please reset the device.
