What is an Archive File? ZIP, RAR, 7z, TAR, GZ (Reviews)

I absolutely certain, if you're using the Internet (file download) or laptop / desktop, even using mobile devices, of course, .zip, .rar, .7z - would like to see the file extension. You may go after confusion, these are the types of files? Actually these are compressed file formats, which are used for archiving! - Now the question is what is the archive file? ZIP, RAR, 7z, TAR, GZ etc. Why file formats are used? From this article you will get a clear idea of ​​all the facts. So, with great breathing, read the article in one breath.

Archive File

You are definitely familiar with the computer folder, right? What is a computer folder? You can say a place where you can copy or move many files at once. When the folder is open, all files are found in it, is not it? Again you can put a folder in any folder, if you copy or move the folder, then folders inside the folder also go with the folder. If it is technically said, you can create a new directory on your computer file system by creating folders. Remember, you have created a new folder in C Drive, say the name of the folder "BDHug", then a directory called "BDHug" will be created and it can be accessed directly from the address "C:\BDHug".
What is an Archive File?
Now, although a computer folder can contain many computer files, but the folder behaves like a directory, rather than behaving like a directory. This means that you will not be able to download a folder, but you will be able to download the files in it. The folder does not have any extension, that is, it is not a file, just the directory.

The archive file works just like a folder, putting together many files like folders together. But it behaves like a complete file without behaving like a directory. Please note that there is an image file in the folder named above, which will be named "BDHug.jpeg" if you want to access this file; "C:\BDHug\ BDHug.jpeg" But if the image is in an archive file, you will never be able to access the image file directly using the address, but you will be able to access the archive file from the address. And since the archive is a file, so it can be downloaded, with a file downloading you will be able to download all of the files in it. Then the address will be "C:\BDHug.Zip" and after downloading the zip file you will get all the files in it as a bandle. Understand?

Why Archive Files are Made?

The first purpose of creating an archive file is to understand you. The main purpose is to store or transfer as a single file easily by inserting many files into one file. If you have downloaded the music album from the Internet, then you must know that a single music file is to be downloaded singly, but if you download the zip archive file, a file contains all the music files, that means you have a zip file You can download and download the complete music album together.


Another great purpose to create an archive file is to call a compression or data compression . Actually, the size of the data is reduced by using the algorithm for saving the computer space, but the information is correct. So what are the files in the archive file, a file contains many files, but usually it's a single file, right? Then it is possible to save the file in style so that it can take up less space. Suppose, there is a text file in the zip file where only "A" is written as data. Although it is a data to us, but to reprint "A" computer, "01000001" has to store 8 bits in the binary. That means the file size is roughly 8 bits, is not it?

Now suppose that it is inserted into a zip archive file and compressed using an algorithm, and remember the algorithm is, if a pattern like "01000001" is seen then the zip file will save the data as "01". Now only those algorithms know that, using a pattern, they make the file smaller, then when the zip file opens, the diameter will be converted to the previous "01000001" file. So, imagine, using algorithms, you could make 8-bit file by creating 2-bit size files, now it will take a lot of space to store it. In this way, 1 GB can be compressed by 10 MB and can be downloaded from online.
Although given the clear idea about the compression from the above paragraph, then there is a detailed article about it, you can check.

Data Backup

In addition to reducing the number of files, downloading and size of multiple files, another special use of archive files is to back up data. Another archive of archive files is that it can contain directory structures. It has its own separate directory structure in the archive file, remember that you have created an archive file from a full folder of software from C Drive, now that archive will retain your entire folder directory structure.

If you extract the archive file again on the C drive, then the previous folder will be returned exactly. That's why the archive file is used to back up web folders from web servers , not just local computer backups. Apart from this, the metadata can be added to the archive file, it is possible to get information about how many backups have been made, some files have been changed after the last backup, etc.

Data Encryption

Another great advantage of archive files is that many files are encrypted together . Since creating an archive file, the algorithm can be used as desired, so it is possible to provide security by encrypting the files using special algorithms. Password or "key" is required to open protected files.
Different archiving tools are encrypted with different algorithms and different sources, so files usually encrypted with one software can not be decrypted by another software. However, some common archives, such as ZIP, RAR, 7z, can be decrypted using many types of software. Yes, if the archive file is encrypted using the AES-256 standard, then almost any archiver software can decrypt it by entering the correct password. ZIP is the most universal, but RAR is widely used.

ZIP, RAR, 7z, TAR, GZ - Why So File Format?

If all archive files do the same thing, why are so many types? Why archive file type formats can be seen? See, different archive file formats can be viewed and made, so that different formats can be used differently. Different algorithms of different formats, compression methods, etc. are different types.
If we talk about Windows XP's program setup file, that means, .exe file, it is also in the archive file, but it does not allow ordinary files to be inserted, but the files needed to run the program are kept in it. In fact, .MP4 or .MKV files are also included in the archive file, Kona is inserted into a file such as audio file, video file, metadata, subtitle file etc. In fact, if a lot of files are inserted in one file, it can be considered as an archive file, although the work is very similar, only the extension is different as per the format.

If we talk about the ZIP Vs RAR file, thus there are some different advantages and disadvantages of each separate extension file. ZIP files, most operating systems start directly from your computer. No separate software is necessary, to create a ZIP or to enclose the inside files. The RAR file uses Better compression techniques from ZIP, but this type of archive file does not directly support Windows or many operating systems. WinRAR archives or 7-Zip archiver software are essential. If you send a RAR file to your friend, he must know that he is working with a type of file. If you do not understand the bat ZIP file, there is no problem, double clicking on the computer will open it like normal folder.
There are 20 files in a folder that you want to mail to a friend, never to mail the folder, you have to send files to one. But because of the archive file you are sending all the files together, and there are many more benefits.
I hope all of the archive files in this article, which you need to know, were discussed. I use 7-zip as an archive, which one do you use? Which is the best archive in your opinion? Please tell us all the comments below.
