What is an extension?

It is known that a compressed file is one or more files that are put together into one and this way the weight of all files in total decreases a bit, leaving more storage space, but what are the extensions of these files?

So, each of the nomenclatures these files can carry is known, these can be seen next to the name you gave the file.

These nomenclatures have a maximum of four letters that go immediately after a period. They are of vital importance recognize with which program this tablet has occurred or simply try to deduce the characteristics it has.

What are these file extensions for?

Specifically, these extensions they help our operating system to know what kind of content can be found in said file, not only that, but also to try to know what it is and above all to try to know with what kind of program it should be to open it when you double click on it .

Unlike the name, which we can change at will whenever we want, the nomenclature of the extensions should not be changed, as would disable the file.
