How to open MDU file?

An often recurring problem with D-Flow FM Model Data Format is that MDU is not associated with the correct program file. This is manifested by the fact that MDU 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 MDU 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 D-Flow FM

The first step is to check if the computer has the D-Flow FM program installed. This can be achieved by typing D-Flow FM 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 MDU files.

Programs to open MDU file

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

Step 2. Create association of D-Flow FM with MDU files

However, it may happen that the application itself does not cause the MDU file to open in the D-Flow FM 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. 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 D-Flow FM application as the default for handling the MDU file.

Step 3. Update D-Flow FM to the latest version

If, despite the association of the D-Flow FM program with the D-Flow FM Model Data Format file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Deltares website or update the program from the application.

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

Very often, the file may be size 0 or incomplete. Usually this applies to MDU files downloaded from the Internet in case the download did not finish properly. 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. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the MDU file that we want to open. However, remember that not every infected MDU file can be recovered, so it is important to take care of regular backups.
Older version of MDU 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. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair MDU file corruption. The easiest way to restore the file is from a backup or by contacting , but this one can be expensive. Not all damage can be reversed.
When reading, a message appears that the file was encrypted or corrupted. The encrypted MDU files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
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. Copying the MDU file to another location will fix the problem.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file MDU to close. However, some background programs may block the MDU file while scanning. If nothing helps, please reset the device.
