Hello dear friends!

The archive is a kind of dimensionless container where you can put as many folders, files and even other archives as you like. Today I will tell you how to create an archive on a computer.

Why is it needed?

Almost everyone who works with a computer has to deal with such a thing as archive. For example, when you need to send a large number of photos through file hosting while maintaining confidentiality. In general, there are a large number of situations when it is necessary to create an archive file:

• Increasing the level of confidentiality of information;
• Additional protection against malware and viruses;
• Sending objects;
• Convenient storage of multiple files;
• Save space on your hard drive.

Archiving programs

To create archive files, special programs are used, which are called archivers. Their main task is to quickly, maximum data compression. It is very important that not a single byte of information is lost during compression. In other words, the selected method must be reversible, then the unpacked data will have the same quality as before the archiving procedure.

There are a lot of archiving applications. However, the most popular of them are the following:

1. winzip
2. WinRAR
3. 7-Zip

Most of these software products have in their arsenal a rich set of various filters and compression methods. Many of them can split large objects into multiple archive volumes and set passwords to open archives. Some applications have customized profiles.

Archiving programs not only help to create an archive document, but also to unpack it. Read about it in my article "".

How to create?

Each archiving application was originally created to work with files of one specific format, however, in order to be able to successfully compete in the market with similar products, they were endowed with functions for working with all types of archives. Therefore, for your purposes, you can install any archiver.

So, let's move on to action. Select what you want to put in archive and right click on it.

A context menu will open in which you will see commands for archiving data (they were placed there by the archiving program during installation on a PC). Choose from two commands:

1. with the help of the first Add to archive...” opens a software window for setting the required parameters.
2. second " Add to archive “current_folder_name.rar” performs this operation using the default settings, and independently gives the name of the archive file (it consists of an extension according to the archiving format and the name of the current folder).

In the first case, you can choose the format, compression level, create a password, name the file, and so on. Having finished all this, you need to click "OK" to start the packaging process. At the end of archiving in the selected directory, you will see a newly created archive document.

To create a self-extracting archive, you just need to check the box “Create SFX archive” in the general settings section of the “Archive name and parameters” window.

Archiving files or folders, most often, is necessary to compress them (reduce the size of the occupied memory) and transfer them via the Internet or removable media. It is more convenient to transfer one archive than each file separately.
There are many programs for creating archives, but the best of them is definitely "Winrar", so now I will describe the process of creating a "rar" archive using this program.

1. We right-click on the file or folder (in our case, select all the photos from the folder). In the context menu that appears, move the mouse cursor to Winrar, and then click " Add to archive…».

2. The Winrar program window will appear. First, let's enter the name of the future archive ( Archive name), as well as the location where it will be saved (to do this, click the " Browse"). By default, all archives are called "New Archive", and are saved to the folder where the archived files are located.

3. Next, proceed to setting the archive format ( archive format). It is best to leave the checkbox in front of the format " RAR”, because it is this format that will open without problems in Winrar archiver(and in other similar programs).

4. Now you need to choose a file compression method. If you have a heavy file, and it does not fit on a flash drive, then you need to compress it using the “Good” or “Best” method, and if it’s just photos, as in the example, then “Normal” will do. Do not worry about the loss of file quality, it is not lost during archiving.

We will not need the rest of the settings to create a simple archive. After configuring all the above features, just click the " OK” and the archive formation process will begin. The time of creating an archive depends on the amount of memory of the archived file (or files, folders).

When you work for personal computer, very often there is a need to reduce the size of a file in order to save space on a hard drive or removable drive. For example, you need to copy a file from one computer to another using a floppy disk. Or you need to send a large file by e-mail.

The process of compressing and packing information is called archiving, and unpacking is called unzipping.

Formats

There are several compressed file formats. The most common are RAR, ZIP, TAR, CAB. It is these three letters that become the extension of the compressed file. The format type affects the degree of compression. For example, a RAR archive weighs less than a ZIP. The format of the packed files also affects the efficiency. Some can be compressed by only two times, while others can be compressed by four or more. There are formats that are not compressed at all. How to create an archive using such a program?

The most convenient tool is a well-known archiver called WinRAR. With it, it is possible to create both ZIP and RAR archives. And it can view and unpack compressed files of other formats without any problems.

If you press the combination CTRL + A, then absolutely all the files in this directory will be selected. If this method is somewhat inconvenient, then you can use the "File" menu of the archiver program. You must select the "Add" item, then in the window that appears, enter the name that the user wants to assign created archive. Here you can also choose the format: ZIP or RAR. The second one is set by default because it compresses much better, and most often there is no need to change it. In the case when you need to transfer the archive to another user, it is better to ask him in advance if he has a program that can work with the selected file format.

Multi-volume archives

Floppy disks are used less and less, but still found. And if you need to record a large archive on them, then it is created as a multi-volume archive. It consists of parts called volumes. How to create an archive of this type? To do this, in the "Volume Size" section, select 1475500. This number indicates the size of the floppy disk. In this case, it is better to check the "For recovery" box so that you can restore the archive if suddenly the data in it is somehow damaged. After all, a floppy disk is not the most reliable drive.

Self-extracting archives

It happens that a compressed file is unpacked on a computer, even if a special program is not installed. How to create a self-extracting archive? To do this, files are selected for packaging, then, by pressing the right mouse button, you need to select the "Add to archive" item. Important: this item is only available when set. Then the format is also selected. In the parameters, you need to specify that this will be an SFX archive. It remains only to click on the "OK" button and everything will be ready.

As you can see from the above, the answer to the question of how to create an archive is not difficult. All you need is the appropriate software, a little patience and direct hands. But the consequences of acquiring skills are only positive: saving space in memory, more free time when transferring files, convenience. You can also teach other beginners. After all, it will also be useful for them to know how to create an archive.

Nowadays, we are accustomed to working with large voluminous files, which sometimes reach several tens or even hundreds of gigabytes.
