How to open MMU file?
The main problem with MyPM Merge Data Format is that the MMU file is incorrectly associated with programs. This is manifested by the fact that MMU 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 MMU 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 myPM Merge
In this case, you should first verify that the myPM Merge application is installed on the computer. The easiest method is to use the system search engine by entering the program name myPM Merge in it. 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 MMU files.
Programs to open MMU file
Remember to download programs supporting MMU files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of myPM Merge with MMU files
However, it may happen that the application itself does not cause the MMU file to open in the myPM Merge 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 displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the myPM Merge application as the default for handling the MMU file.
Step 3. Update myPM Merge to the latest version
The fault may also lie with the myPM Merge program, it is possible that MyPM Merge Data Format requires a newer version of the program. Some applications allow you to update from the program level, and for others you need to download the installer from the Midori Media page and install.
Step 4. Check for the following problems with the MMU file
The problem may also be with the file itself if the above steps don't work. The most common file problems are:
The affected file may be 0 KB or smaller than expected. This suggests truncating the MMU file contents when downloading or copying. The only repair option is to download the file again.
The most common cause here is computer viruses. 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 MMU file that we want to open. Sometimes virus-infected MMU files cannot be recovered, so make a backup in advance.
Older version of MMU 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 MMU file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Midori Media
The program indicates that the file is encrypted or corrupted. The encrypted MMU 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. It is best to move MMU to a different directory.
This can happen on a file that does not support multiple access. Some file types can only be opened in one program at a time. Just close unnecessary programs. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the MMU file for a certain period of time. If the problem persists, restart the machine.
