.EX_ Files

The .EX_ file extension is the file type for the EPM Macro File. This is relatively uncommon file extension because file extensions are usually identified by three characters - this file extension's more well recognized form is the .EXE file extension

.EX_, EXE and EPM are used to refer to application or otherwise "executable" files. The .EX_ file extension is basically identified with the EPM macro file that is created by Rexx macros or various components of the Enhanced Editor Toolkit and Accessories.

EMP Macros are actually a series of commands and actions that are implemented in order to automate tasks within an application. The execution of macros is handled by systems that can interpret the stored commands the self-contained programs that are usually built into more complex applications.

.EX_ files are compiled macros that are interpreted during the runtime cycle of your PC or laptop and can be controlled in two different ways. The first is by the creation of mycnf.e and setting flags for the different features already defined within the EXE file. The second is for the user to write his or her own macros. The Emptech database serves as the macro programmer’s technical reference guide in order to effectively implement EMP macros.

Opening .EX_ Files

There are two circumstances where you will encounter .EX_ files, the first is when you boot up your PC or laptop. You won't actually see the .EX_ files that have started the boot cycle, launched the operating system or the various applications automatically launched when you start your computer. In this case the .EX_ files are part of the "behind-the-scenes" activities which enable all of the functions of your PC or laptop to operate as a cohesive unit.

The second situation is one where you will have much more of an active role in the opening or launching of an .EX_ file - that is when you click to open a software application within the operating system environment or click to open an application within the windows explorer environment (not to be confused with the I.E browser - this is the "file manager" view of the folder structure on your computer).

.EX_ files are the most basic of all file types to open - because they are self executing files. In simple terms once you double-click on an .EX_ file it will automatically launch and execute the code within the application.

Common Problems With .EX_ Files

The .EX_ files is a universal file type that will open within both the Windows and Mac OS operating environments - and herein lies the power and the problems with executable files. Their power stems from their ability to self-execute and run complex codes need to create the interface of the installed application - think of any application (MS Word, FireFox, Windows Media Player, Adobe Acrobat, Outlook etc.) currently installed on your PC or laptop - in every single case it takes an .EX_ file to open and launch the features of that software application. EX_ files are the incredibly diverse and powerful codes behind every application your computer uses.

The problems with .EX_ files are equally great - because they are self-executing files and essentially run in the background on your PC or laptop you have absolutely no control of what they do once you open an .EX_ file. There is incredible risk that a virus, spyware, adware, malware or some other destructive piece of code could be hidden in the .EX_ file and do serious harm to your computer.

If you are unable to launch your applications or your computer is experiencing problems booting up, experiencing general system crashes or a general slowdown then you may be faced with a known problem with .EX_ files and the Windows Operating System - a malfunctioning or corrupted Windows Registry. Fortunately most file extension-related errors can be easily resolved by running a Windows Registry Optimizer which cleans the Registry and repairs many of these types of problems. These programs also tend to keep the Windows Registry working efficiently, speed up the PC or laptop and generally keep the computer functioning smoothly.

Security Threats With .EX_ (EPM) Macros

As alluded to above, the distinct mechanism an .EX_ file automatically runs an EMP macros when it is opened which allows the spread of viruses that can be sent (not necessarily with your knowledge) through e-mail or other forms of file transfer. Without the protection of an effective anti-virus application that can detect macro viruses, a potentially dangerous virus can create an epidemic.

Some applications have a built-in security feature to help prevent the spread of macro viruses. However, this is only effective if the application itself has not been infected. The most efficient and effective way of containing and preventing such problems is to run an updated anti-virus software application on your system in conjunction with best security practices.

The most common way that macro viruses infect files is by replacing the normal macros contained within clean documents with contaminated macros that are spread via email attachments, networks, modems, discs and the Internet. The macro virus works by replacing the regular commands with another of the same name. It then waits until you give it the normal launch command and it activates.

Macro viruses are application-dependent as opposed to operating system-dependent viruses. This means they have the capability of infecting a computer running on every type of operating system environment. For example, Microsoft Word (which is supported not only by Microsoft Windows but also by Mac OS) can have a document that has a macro virus shared between the two computers. This causes both systems to be infected.

Macro viruses are executed soon after opening the infected document. It will then proceed to infect the system, embed itself into other templates, and even infect files that have yet to be created unless it is removed from the system. The Melissa Virus is a classic example of a macro virus that had spread by attaching itself to a document. Upon infection of the system, it had sent itself via email to the first 50 entries in the user’s address book. This accounted for the vast and quick replication rate of the virus.

It is important to implement security precautions to ensure that they are not only stopped from spreading but also totally eradicated from computer systems. Installing a dependable anti-virus software program and regularly scanning files (especially downloaded files or data sent as email attachments) are effective ways to protect not only your computer system but also other computers connected to your network.

Be Aware - Beware!

Be wary of opening .EX_, or any other file for that matter, sent by someone you do not know or one you downloaded off the Internet. Opening unknown .EX_ files can present the danger of virus infection, spyware and/or malware. Before opening one of these file extensions ensure it comes from a source you trust, that you have good anti-virus, anti-spyware, spam controls, privacy software, a registry cleaner and trusted data recovery tools activated and protecting your system.

Be sure to regularly scan attachments and all files in your computer system with an up to date anti-virus application or anti-spyware software, and ensure that it is really safe to open the .EX_ file.
