EXECUTABLE FILE EXTENSIONS  Types ▷ 2020

A computer is much more complex than any user could imagine. If you knew its history and evolution, you would really be surprised with what we have been able to achieve today. And among the many advances, today we want to talk about executable files.

These are special files that have the particularity of working by themselves, simply using an operating system, without having to install programs. In fact, they are the elements that make a program conform and appear out of nowhere (in many cases).

Are you curious? Do you want to learn more about executables? Although it can be a bit complex in terms of vocabulary, we are going to explain it in such a way that, when you finish the text, you are, yourself, capable of explaining what this resource consists of and you can get an idea, looking at your folders, of which ones they are. and which ones are not.

What are executable files and what are they really for?

The executable file, always referring to computing, is that file that, due to its own characteristics, can be interpreted by a machine without requiring specific programs for it. Is that it will be the computer itself that recognizes and executes it thanks to its composition. It is based on basic instructions own according to their purpose.

The usual thing is that, at the same time, binary and include scripts (They also have instructions that other software will interpret), although it does not always have to be that way. Its basis is instructions in machine code for specific processors.

In some cases, we also find bytecode in need of interpretation for what would be known as “making system calls”, something more complex but that also happens every day when we use a computer.

Be that as it may, if it is accompanied by others digital files, the executable will be the one that starts its execution, loading and handling.

We can classify them in:

  • Portables. Its execution is available on various platforms.
  • Not portable. This execution can only be carried out on the platform for which the file was designed.

what is executable file

What we can conclude is that the concept has become ambiguous, or quite the opposite, because, as we advance in computing, the characteristics of the files have been changing, evolving to create more complex files that make classification fuzzy between a mere executable and a more complex script or file.

In the end, what we can determine is that the essence of this is that inside it has the instructions to be executed, these are not conferred or used by any other type of file or program, although it is true that, in addition to these, we can find extra information in some cases.

Self-executing files

Within these we can differentiate what we call files self-executing. These have the necessary instructions so that they themselves can do the tasks entrusted to them.

There is no original software necessary for this, but they can start to work on any computer regardless of what they have installed both in the system and afterwards.

Beware of executable files! The whole group is dangerous in its own right by its very nature. However, the autorun is even more attractive to that the cybercriminal on duty convert it into malwareBeing, as you can suppose, the contagion of the equipment much faster and easier, since it does not require action by the user or specific elements.

Difference between executable files and non-executable files

We begin by indicating that the executable works by itself, running by the computer and carrying out tasks according to coded instruction.

The non-executable is an information container file; It is not executed by the machine but by a specific program for it (an image with a viewer or an editor, an audio with a player, etc.) and the task it has is specific. In fact, the computer cannot carry out said execution.

The types are, on the one hand, scripts or compiled and, on the other, text files, spreadsheets, videos, databases. That is, the latter are contained data that can be displayed to user Y, possibly, Modify if you have the necessary (extra) tool.

Types of executable file extensions and their associated programs to open them

On this occasion we cannot, as we always do, show you in the table, what softwares are used to open these types of files, as we have already seen, they do not need them. What we will show you are some of its features and operating system where they work.

As we always say, the table is made up of those most famous or functional executable files, but there are many more. Although, for a conventional use of a computer, knowing these will be more than enough for you to consider yourself a user above average in this regard.

System / Program Features Extension .exe
