How to open MDUS file?

The most common problem when using MessengerDiscovery is that a specific MDUS is not associated with the program. This is manifested by the fact that MDUS files open in unusual applications or do not have an assigned program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the MDUS 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 MessengerDiscovery

In this case, you should first verify that the MessengerDiscovery application is installed on the computer. This can be achieved by typing MessengerDiscovery into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support MDUS files.

Programs to open MDUS file

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

Step 2. Create association of MessengerDiscovery with MDUS files

However, it may happen that the application itself does not cause the MDUS file to open in the MessengerDiscovery 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. Using the "Change" button we can select the desired program. 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. Checking the "Always use the selected program ..." box will permanently associate the MDUS file with the MessengerDiscovery program.

Step 3. Update MessengerDiscovery to the latest version

If, despite the association of the MessengerDiscovery program with the MessengerDiscovery file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Matt Holwood page and install.

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

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The MDUS file may be unusually small compared to the original file. Usually this applies to MDUS files downloaded from the Internet in case the download did not finish properly. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. The scan should cover the entire computer, not only the MDUS file that we want to open. Sometimes virus-infected MDUS files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the MDUS file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair MDUS file corruption. The easiest way to restore the file is from a backup or by contacting Matt Holwood, but this one can be expensive. Not all damage can be reversed.
The program indicates that the file is encrypted or corrupted. The encrypted MDUS 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 MDUS file to another location.
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 MDUS 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.
