What is a MEX file?

MEX files mostly belong to Macro Express by Insight Software Solutions. MEX stands for Macro Express file. MEX file is used as a data file in the Macro Express application developed by Insight Software Solutions.

• Main Use: Macro Express is a Microsoft Windows compatible application that is used in the recording, editing, and playing back of macros created using keyboard strokes and mouse clicks. Macro Express uses MEX files to facilitate the automation of repetitive tasks in Windows PCs. Each MEX file consists of macros i.e scripts and commands, that are auto-executed when run. Some MEX files come pre-installed with the software and have the file name sample.mex.
• Other Uses: MEX files are also used by MATLAB, a scientific computing application developed by Mathworks and is used for developing algorithms, plotting graphs, analyzing data, and performing numeric calculations. These MEX files contain dynamically linked subroutines used by the macOS version of MATLAB software. MEX files are also used as data files by the Corel WordPerfect software that is bundled with the Corel WordPerfect Office suite. These MEX files store expound data that can be utilized by Macro Editor present in the Corel WordPerfect application.

MEX file format:

A file format defines how the data in the file is structured. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. Our evaluation of the MEX files looks like this:

The MEX file extension is not widely used. Such a file includes a lot of different file formats for different programs. The following file formats are most commonly found in MEX files:

• 15% of all MEX files save the data in Java file format. This format is used to save Java objects to a file (ex. save game state as file) via object serialization. Such a Java object may contain functions and data like settings, images or videos. The contents of these files are partially readable by a human. Most of these files are 13 KB to 290 KB in size. The following keywords are characteristic: Ljava/lang/String;L, Ljava/util/GregorianC, authorNamet, dateCreatedt, displayAnswersI, examDurationZ, excelentities.ExamExcel, mrqI, numberOfQuestionsI, passMarkZ, takenZ and theoryL. An example of a file name is GSE202EXAM.mex or AGY303.mex. These files can be linked to exam.
• 8% of all MEX files are associated with Macro Express Macro. These files contain neither text nor words, but only data. MEX files are between 7 KB and 210 KB in size.

The remaining 77% of all MEX files are files with no common format, the following 5 formats can be found: XML and EXE. These files sometimes refer to tarama, kiranlar, macderkenuyari, gentarama or level.
