Compressed FILE EXTENSIONS  What are they and types? ▷ 2020

Who has not found a .zip or a .rar on some occasion? These files are very common in the day to day of all those users who operate on a computer, especially if they connect to the internet. These include what is called a compressed file extension.

These serve to indicate many things and appear when the user joins, with some software, different files in a single file. Some files of this type must be decompressed but others allow you to access their content without the need for it.

Does all this sound like something to you? Let’s see, in any case, what is a file extension compressed, what is it used for, which ones exist, how are their characteristics and how can we open these groups of files.

What is the extension of a file or compression file and what is it really used for?

what is compressed file extension

A compressed file is one that has been worked on so that it occupies less space than all of its parts. That is, it is a set of files that compress to take up a single space and weigh less, so that they are all grouped together and are easy to move. Thus an extension of this type of files It will be the one that serves to define them as such.

It is part of the nomenglature that is given, in this case, to a set of compressed files so that our system knows that it is, precisely, a set, that is, that we must work on them to define them and see what type each is within the set.

This name follows the name you give the tablet and consists of a set of between 1 and 4 letters and / or numbers; they go after a period, like the rest of the extensions.

When we see them, we know with which program the compression was done and, therefore, what we can expect from that file: if it will decompress fast, if it has been transformed, if our compression software is compatible, etc.

These are characteristics are achieved for the file at the time it is being created, that is, when we are putting all its parts together and compressing them, depending on the program used For this, one or the other results will be obtained.
