MEX4 File Extension

What is MEX4 file?

MEX4 filename suffix is mostly used for Sun-4/SPARC Dynamically Linked Subroutines files. Sun-4/SPARC Dynamically Linked Subroutines specification was created by MathWorks, Inc.. MEX4 files are supported by software applications available for devices running Windows. Files with MEX4 extension are categorized as Misc Files files. The Misc Files subset comprises 6033 various file formats. The most popular software that supports MEX4 files is MATLAB. MATLAB software was developed by MathWorks, Inc., and on its official website you may find more information about MEX4 files or the MATLAB software program.

Programs which support MEX4 file extension

The following listing features MEX4-compatible programs. Files with MEX4 extension, just like any other file formats, can be found on any operating system. The files in question may be transferred to other devices, be it mobile or stationary, yet not all systems may be capable of properly handling such files.

How to open file with MEX4 extension?

Being unable to open files with MEX4 extension can be have various origins. On the bright side, the most encountered issues pertaining to Sun-4/SPARC Dynamically Linked Subroutines files aren’t complex. In most cases they can be addressed swiftly and effectively without assistance from a specialist. The following is a list of guidelines that will help you identify and solve file-related problems.

Step 1. Install MATLAB software

The most common reason for such problems is the lack of proper applications that supports MEX4 files installed on the system. The solution is straightforward, just download and install MATLAB. On the top of the page a list that contains all programs grouped based on operating systems supported can be found. If you want to download MATLAB installer in the most secured manner, we suggest you visit MathWorks, Inc. website and download from their official repositories.

Step 2. Update MATLAB to the latest version

If you already have MATLAB installed on your systems and MEX4 files are still not opened properly, check if you have the latest version of the software. It may also happen that software creators by updating their applications add compatibility with other, newer file formats. The reason that MATLAB cannot handle files with MEX4 may be that the software is outdated. The latest version of MATLAB should support all file formats that where compatible with older versions of the software.

Step 3. Set the default application to open MEX4 files to MATLAB

After installing MATLAB (the most recent version) make sure that it is set as the default application to open MEX4 files. The method is quite simple and varies little across operating systems.

The procedure to change the default program in Windows

• Clicking the MEX4 with right mouse button will bring a menu from which you should select the Open with option
• Next, select the Choose another app option and then using More apps open the list of available applications
• Finally select Look for another app on this PC, point to the folder where MATLAB is installed, check the Always use this app to open MEX4 files box and conform your selection by clicking OK button

The procedure to change the default program in Mac OS

• Right-click the MEX4 file and select Information
• Proceed to the Open with section. If its closed, click the title to access available options
• Select MATLAB and click Change for all...
• Finally, a This change will be applied to all files with MEX4 extension message should pop-up. Click Continue button in order to confirm your choice.

Step 4. Check the MEX4 for errors

If you followed the instructions form the previous steps yet the issue is still not solved, you should verify the MEX4 file in question. Problems with opening the file may arise due to various reasons.

1. Verify that the MEX4 in question is not infected with a computer virus

If the file is infected, the malware that resides in the MEX4 file hinders attempts to open it. Immediately scan the file using an antivirus tool or scan the whole system to ensure the whole system is safe. MEX4 file is infected with malware? Follow the steps suggested by your antivirus software.

2. Check whether the file is corrupted or damaged

If the MEX4 file was sent to you by someone else, ask this person to resend the file to you. It is possible that the file has not been properly copied to a data storage and is incomplete and therefore cannot be opened. When downloading the file with MEX4 extension from the internet an error may occurred resulting in incomplete file. Try downloading the file again.

3. Ensure that you have appropriate access rights

Some files require elevated access rights to open them. Switch to an account that has required privileges and try opening the Sun-4/SPARC Dynamically Linked Subroutines file again.

4. Check whether your system can handle MATLAB

The operating systems may note enough free resources to run the application that support MEX4 files. Close all running programs and try opening the MEX4 file.

5. Verify that your operating system and drivers are up to date

Up-to-date system and drivers not only makes your computer more secure, but also may solve problems with Sun-4/SPARC Dynamically Linked Subroutines file. It is possible that one of the available system or driver updates may solve the problems with MEX4 files affecting older versions of given software.
