To all of us who are always on our computers and smart devices, there has not come a time when we come across different compressed files, especially if we participate in a common way in different file downloads by using the internet or transferring files. . data.
Well, these compressed files can sometimes have the calls “extensions” which are generally known when a user associates it with a completely different software to original file, learn here all about compressed file extensions.
What are these file extensions for?
More specifically, these extensions help our operating system so you know what kind of content can be found in said file, Not only that, but also to try to know what it is about and above all to try to know with what type of program you should open it when you double click on that.
Unlike the name, that we can change to our liking whenever we want, the nomenclature of the extensions should not be modified, as would disable the file.
What is a compressed file?
It is known that a compressed file is a file or several that are put together in one and in this way the weight of all the files in total decreases a little, leaving more storage memory, but What are the extensions of these files?
Each and every one of the nomenclatures is thus known What can these files carry?, can be displayed next to the name you have given the file.
These nomenclatures have a maximum of four letters that immediately follow a period. They are of vital importance to recognize with which program this tablet has been produced or simply to try to deduce the characteristics that it has.
In a nutshell, we could define a compressed file like result of a procedure what to do with a catch, file or document in question. The main objective of this procedure is to reduce its size and weight so that it takes up less storage space on the device.. A very important point to note is that in this process we do not lose the original content of the file, namely, remains intact only with less weight.
When compressing the files there is the possibility to create a password for your login, which will allow only selected users to display existing content within the folder or document. Those who have the password will be able to unzip and access them in a few simple steps.
Its main function is reduce storage space, to allow a greater flow of information. This procedure is also carried out very regularly to reduce the weight of a file and be able to send it by email, Through social networks, and even move it to a pendrive. Also with this function you can download several files and send them in a single folder, which will facilitate its download at the time of requesting the information.
How a compressed file works
This procedure generally It consists of two states: Yes and no. Know that it does not represent a negative state, which means that it means absence and is one of the options present in the algorithm. While the yes, represents a positive state and is also part of the algorithm. Both belong to a binary code, which is a language used by machines.
However, throughout evolution these machines were adapted to a much more complex system. Hence originates what we know today as programming. These codes are written in spoken language and the system automatically takes care of translating them into your code in a very simple way.. For this reason, when compressing the system receives a raw code, that the system can detect and summarize in seconds. To allow the file to gain less weight.
Types of compressed files that exist
Only for compressed files There are two kinds which we will explain in detail below.
First of all we do not find the lossless compression or also known as lossless compression, this compression works in a nutshell by eliminating redundancy, namely, if there is continuous repetition of an algorithm, the system automatically takes care of synthesizing it and converting it into a less heavy file. significantly reducing repetitions and the space it occupies.
We also have the lossy compression, that is to say that in its process it leaves part of its lost information. What in one way or another directly affects the state of the file. In general, This is the most used in the audiovisual format and is usually very effective in that branch.
Nomenclatures
There are a variety of extensions.Thus, we will show you the most common, together with the program with which you should unzip it on your mobile or PC.
.arco
This is one of the oldest formats of all and is currently exclusive only for use on computers. It should be opened with programs like, OpenUp o Stuffit.
.arj
Arj is a flexible function format that came to light over the years 90, sadly it's a slow decompression, So it is currently in disuse. Uncompressed with 7-ZIP The PeaZIP.
.compartment
This together with .hqx, they are currently generic and have a high compression capacity, must become binary. For Mac devices it is not necessary to use a program, but for other systems it is ideal to use PeaZip.
.Postal Code
ZIP It is one of the standard extensions of Windows and DOS, it's really fast but less compression than many others. Unzipped using WinRAR or 7-ZIP. You can also open or send a ZIP file by WhatsApp
.rar
Unlike .zip, This is from high speed at the moment of compression, but it's slow to run. It is also one of the most used today. It is decompressed by programs like WinRAR, WinZip, 7-ZIP o iZIP, the latter in case you use Mac.
.AS
Has an excellent compression and decompression ratio, it is also very fast and highly compatible with long names. It is decompressed with programs like WinACE, Windows Commander Y PCTools.
.uu o .uue
It is very common to find these email extensions, convert binary files to texts and 7 bits. The WinRAR or WinZip program is used, but normally it can be done automatically.
.gz o gzip
Used in PC and UNIX files, has a deflation algorithm, which manages to combine huffman and LZ77 encoding. Unzips using freeware and shareware, What, Spread, Coldcompres Y freeze it.
.O is .sitx
This is an extension of the Stuffit program, which is very versatile and also, with a considerably good compression speed. It decompresses using programs like Stuffit Deluxe or Stuffit Expader for Windows.
.to be
This extension is exclusively for MacOS devices and is unzipped without the need for special programs or applications.
