Before continuing, it is important to know what an extension is and what it does in operating systems. These extensions are very varied and can work in different programs as long as you are compatible with them.

The extension of a file is made up of the set of three or four characters. These are in the final part that constitutes the name of the file as for example; .html, .docx, .txt. These tell the system and experienced users what type of file it is and, in turn, tell the operating system which programs can open them.

Commonly a default program is associated for each file extension, where just by clicking on the file it will start automatically and in turn will allow the user to observe and edit it if desired. A clear example of this is Word and other word processors, since depending on which one you have installed and you have indicated as default, it will be the one that starts when the file is opened.

When the program that allows it to work the file extension is no longer on the computer, the associated file cannot be opened many times.
