What is MMK file?

The file with the extension MMK is the Settings Files file type. It was designed by Prof. RNDr. Jiri Kolafa, CSc.. In addition to this file, the Settings Files category includes 1305 related files. MACSIMUS Define is supported by 1 operating systems. These systems consist of Windows, although it may occasionally be found on another system, it will be non-functional. It is recommended to use MACSIMUS to handle this file. This is a program created by Prof. RNDr. Jiri Kolafa, CSc..

How to open MMK file?

An often recurring problem with MACSIMUS Define is that MMK is not associated with the correct program file. This causes the file MMK to open by system applications not designed for this purpose, or to display a message that there is no associated program. How to solve such a problem?

The first thing you should do is just "doubleclick" on the MMK 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 MACSIMUS

The first step is to check if the computer has the MACSIMUS program installed. The easiest method is to use the system search engine by entering the program name MACSIMUS in it. 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 MMK files.

Programs to open MMK file

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

Step 2. Create association of MACSIMUS with MMK files

If, despite the installed application, the MMK file does not start in the MACSIMUS application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of 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. Checking the "Always use the selected program ..." box will permanently associate the MMK file with the MACSIMUS program.

Step 3. Update MACSIMUS to the latest version

If, despite the association of the MACSIMUS program with the MACSIMUS Define file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Prof. RNDr. Jiri Kolafa, CSc. website or update the program from the application.

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

The problem may also be with the file itself if the above steps don't work. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This suggests truncating the MMK file contents when downloading or copying. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. For the best results, we will scan the entire operating system, not just our MMK file. As a result of the scan, sometimes it is not possible to recover MMK files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
This can happen especially when the program is dynamically developed and the structure of the MMK files changes over time. 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.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Sometimes the program itself has options to repair the most popular MMK file corruption. The easiest way to restore the file is from a backup or by contacting Prof. RNDr. Jiri Kolafa, CSc., 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 MMK 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. These directories are write-protected to them and it's very hard to fix this problem. Copying the MMK file to another location will fix the problem.
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. Some anti-virus or backup software may occupy the MMK file for a certain period of time. If this does not work either, restart the device.
