Tips to open MEX4 file
Can't open the MEX4 file? You are not the only one. Thousands of users face similar problems every day. Below you will find tips on how to open MEX4 files as well as a list of programs that support MEX4 files.
MEX4 file extension
| File Name |
Sun-4/SPARC Dynamically Linked Subroutines |
| File Developer |
MathWorks, Inc. |
| File Category |
Misc Files |
The MEX4 file is supported on 1 operating systems. Depending on your operating system, you may need different software to handle the MEX4 files. Below is a summary of the number of programs that support and open the MEX4 file on each system platform.
What is MEX4 file?
The file in the MEX4 format belongs to the Misc Files category. The creator of this file is MathWorks, Inc.. In addition to this file, the Misc Files category includes 6033 related files. Sun-4/SPARC Dynamically Linked Subroutines appears on 1 operating systems as a functional file. Although it can be found with greater or lesser success on any operating system, it will only be useful on Windows. The main program that supports this format is MATLAB. This was created by MathWorks, Inc..
How to open MEX4 file?
The main problem with Sun-4/SPARC Dynamically Linked Subroutines is that the MEX4 file is incorrectly associated with programs. This causes the file MEX4 to open by system applications not designed for this purpose, or to display a message that there is no associated program. This can be quickly resolved by following the instructions below.
The first thing you should do is just "doubleclick" on the MEX4 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 MATLAB
An often overlooked issue is to make sure that MATLAB is installed on the computer. This can be achieved by typing MATLAB 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 MEX4 files.
Programs to open MEX4 file
Remember to download programs supporting MEX4 files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of MATLAB with MEX4 files
If, despite the installed application, the MEX4 file does not start in the MATLAB application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. 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. However, it is important to check the "Always use the selected program ..." box, this will allow you to permanently associate the MEX4 file with the MATLAB application.
Step 3. Update MATLAB to the latest version
The fault may also lie with the MATLAB program, it is possible that Sun-4/SPARC Dynamically Linked Subroutines requires a newer version of the program. This can be done using the application (if it provides such options) or from the MathWorks, Inc. website and install the latest version.
Step 4. Check for the following problems with the MEX4 file
If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:
The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the MEX4 file. The file should be downloaded again, making sure that the process has finished correctly.
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 MEX4 file. Sometimes virus-infected MEX4 files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the MEX4 file. 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 MEX4 file corruption. You can restore the file from a backup or use MathWorks, Inc. help.
The program indicates that the file is encrypted or corrupted. The encrypted MEX4 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 MEX4 file to another location.
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. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the MEX4 file for a certain period of time. If nothing helps, please reset the device.
