What is MMDL file?

The file in the MMDL format belongs to the 3D Image Files category. It was designed by MITEK HOLDINGS, INC.. In addition to this file, the 3D Image Files category includes 622 related files. SAPPHIRE Structure Model is supported by 1 operating systems. The file will work on Windows systems, unfortunately not on others. The main program that supports this format is SAPPHIRE. This was created by MITEK HOLDINGS, INC..

How to open MMDL file?

An often recurring problem with SAPPHIRE Structure Model is that MMDL is not associated with the correct program file. Thus, when you open MMDL, the program selection wizard or some other program starts. This can be quickly resolved by following the instructions below.

The first thing you should do is just "doubleclick" on the MMDL 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 SAPPHIRE

An often overlooked issue is to make sure that SAPPHIRE is installed on the computer. This can be achieved by typing SAPPHIRE into the operating 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 MMDL files.

Programs to open MMDL file

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

Step 2. Create association of SAPPHIRE with MMDL files

However, it may happen that the application itself does not cause the MMDL file to open in the SAPPHIRE 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. 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. The "always use the selected program ..." field will set the SAPPHIRE application as the default for handling the MMDL file.

Step 3. Update SAPPHIRE to the latest version

If, despite the association of the SAPPHIRE program with the SAPPHIRE Structure Model file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the MITEK HOLDINGS, INC. website and install the latest version.

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

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The MMDL file may be unusually small compared to the original file. This suggests truncating the MMDL file contents when downloading or copying. Downloading the file again should fix the problem.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. 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 MMDL file. Sometimes virus-infected MMDL 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 MMDL 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. Sometimes the program itself has options to repair the most popular MMDL file corruption. The easiest way is to restore the file from a backup, if there is one, or contact MITEK HOLDINGS, INC.
The program indicates that the file is encrypted or corrupted. The encrypted MMDL 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. These directories are write-protected to them and it's very hard to fix this problem. If possible, you can try to move the MMDL 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. Closing other programs should help. If the error persists after closing other programs, wait for a while. However, some background programs may block the MMDL file while scanning. If the problem persists, restart the machine.
