Compressors - decompressors. What they are, what they are for and which file compressor to choose

File compression
Users with some experience will know very well what a compressor is and what it is for, however many people who start with computers are strangers to terms like unzip, zip file, decompressor, or compressor.

Today we are going to see a small explanation about what a compressor is fundamentally and what it is for. In this way later we will be able to see which compressor to choose for our daily use and how to install it. Before continuing I want to clarify that from now on when referring to a compressor I will be referring to a program that allows both to compress and decompress since nowadays all the programs that compress do the opposite operation of decompressing.

What is a file compressor?

File compression formats

Un file compressor is a program that allows you to reduce (compress) the size of a file. (For example, reduce the size of a PDF) This is achieved through a series of algorithms that allow the data contained in a file to occupy less size without loss of information. I am not going to go into how a compressor can reduce the weight of a file since it is a complicated topic that is outside the scope of this article, which is aimed at those who begin in computing, but those who are interested can read more by searching on data compression.

BWell, as I said before, when we talk about a file compressor, we understand that it includes the ability to decompress compressed files. As regards the previous definition, it must be added that the compressor is also capable of restoring the compressed file to its original format (decompressing). You might wonder And why not leave the file compressed and thus take up less space all the time?. The problem is that when we compress a file it changes its format, its structure, and it can only be handled by compressors. For example if you have a text document with PDF extension that you can open with the program Foxit PDF Reader and you compress it with a file compressor and you won't be able to open the document until you unzip it.

EThe latter happens because when you compress a file its extension changes. Let me explain, for example in a file called "my_program.exe" the extension is ".exe»And when you compress it it will change to« my_program.zip»Or« my_program.rar»Depending on the compression format you choose. The most common compression formats are these two (zip and rar), but there are many others such as: 7-ZIP, A, ACE, ARC, ARJ, B64, BH, BIN, BZ2, BZA, C2D, CAB, CDI, CPIO , DEB, ENC, GCA, GZ, GZA, HA, IMG, ISO, JAR, LHA, LIB, LZH, MDF, MBF, MIM, NRG, PAK, PDI, PK3, RPM, TAR, TAZ, TBZ, TGZ, TZ , UUE, WAR, XXE, YZ1, Z and ZOO.

Most compressors will allow you handle any of these formats although if your operating system is Linux, in this guide we will show you how install tar.gz.

What are file compressors for?

File compressors

Apart from the space that we save on the hard disk when we have a compressed file, the fundamental utility of a file compressor is appreciated when sending files from one computer to another. If you ever had to send a file by email and the program told you that the file to send was too large, you will be glad to know that with a compressor you can reduce the file size to be able to send it by mail. We already know that when it comes to sharing files over the network, the larger their size, the longer it takes to send or download them. So by compressing the files we will gain, in addition to storage space, time in sending and downloading files.

BWell, we already know what a file compressor is for and what it's for, now it's time to decide which one to choose. One of the compressors - most common decompressors is WinZip, which is paid, the most widespread and used alternative is WinRAR, but it is also paid. On the other hand, free file compressors are becoming more and more known that allow us to do practically the same things that we would do with one of the paid ones but free. Honestly, the functions that a normal user uses are simply zip and unzip and these free programs perform these functions more than anything. If in addition to free they are in Spanish the thing opts not to pay a penny to use a compressor. I recommend that you take a look at both 7-Zip as IZArcBoth are free, they are in Spanish and you can easily compress and decompress with them.

Si are interested in install a free and very complete compressorread this IZArc installation manual, in it you will see how to install the program step by step. Soon we will see in another tutorial how to access the main functions of the program. Until then I hope it has been clear to you what a compressor-decompressor is for and that the article has been useful to you. Vinegary greetings to all.

  22.   Agustin said

    Hello thanks for the information
    It served me a lot because I did not understand
    nothing haha ​​.. but I have a question:
    Can you compress music to pass
    to a cell phone like that takes up less? ...

    See ya…

    Agustin

  23.   Killer Vinegar said

    Agustin the compressors do not have that function. What you want to do you have to do with a converter (not compressor) that allows you to lower the bitrate of your songs.

  44.   seba64 said

    Hello, as someone already asked, I would like to know if someone knows how to compress a thm file to put it as a theme on a cell phone. The thm files are the themes that I can choose on my cell phone (a sony ericson) and thus change the background colors and images. I can take a thm file from the cell phone and take it to my pc, decompress it with any program, modify the colors and images, but I need to compress it again to put it on my cell phone. So does anyone know how to compress a folder to a thm file?
