Many programs we download from the Internet are zipped (packaged) to reduce their size. Those. programs are in the archive. Before installing a program from an archive, it must be unpacked (there are exceptions to this rule). Here is an example of installing a program for checking texts for plagiarism, which after downloading is in the archive.

Option 1. Only the ZIP archiver is installed on the computer

So, after downloading, a ZIP archive appears in the downloads folder.

Please note that the archived file appears differently than regular folder. There is a lightning bolt on the archived folder. We can easily look into the archive folder and see in it the files necessary to install the program.

Alas, if we try to start the installation by clicking on the setup icon, the installation of the program will not begin, but a message will appear "This application may be used by others compressed files, stored in this folder. To run the application correctly, you must first extract all files."

In a specific case, to install the program, you can run not the setup file (setup.exe), but the EtxtAntiplagiat file ( EtxtAntiplagiat.msi). However, in some cases it is necessary to extract all files from the archive, and only then proceed with installing the program. To extract files use the button Extract all(see previous picture).

By pressing the button Review, you can select the location where the archive will be unpacked. As an example, let's unpack the archive into the Program folder, which we will create on the desktop.

Now you can safely begin installing the program. After double click by icon setup The installation process of the program will begin.

After double clicking on the setup icon, the installation process of the program will begin

If installed on your computer WinRAR archiver, then the actions will be slightly different.

Option 2. WinRAR archiver is installed on the computer

As a rule, after installing the WinRAR archiver on your computer, it becomes the default archiver, i.e. all archive files will open when WinRAR help. If the WinRAR archiver is installed on your computer, the archive files look like a stack of books tied with a belt.

The WinRAR archiver is a much more advanced program than the ZIP archiver that comes with Windows. In a specific case, WinRAR allows you to install the program by running the setup.exe file, even without unpacking the archive into separate folder. If you still need to unpack the archive, then context menu(called right click mouse) you can select a location to unpack the archive.

For example, if you select the Extract to etxt_antiplagiat\ option, then a folder matching the name of the archive will be created in the downloads folder, into which the files extracted from the archive will be placed.

If you still have questions about installing programs from the archive, ask them in the comments.

Today we will look at archiver 7-Zip. The developer of this program is also Russian programmer– Igor Pavlov, as in the case of , because it was also created by the Russian team.

Zip is a common compression algorithm, but in fact the 7-Zip archiver is very different from this method in terms of file compression, despite the fact that this word is used in the name of this program.

Files zipped into an archive using the 7-Zip program have a 7z extension if you leave the default settings. But when adding files to the archive, you can change this format to zip, tar and others. We will look at how this is done when creating archives.

Despite being free, the program provides a good compression ratio, no worse than the paid one. WinRAR programs. Download latest version can be found on the official website.

After installing the program, we need to run it. As I understand it, it does not create a shortcut on the desktop, so to launch it you will have to find it in “Start”.

The main window of the program is very simple. At the top there are various menus, below there are large buttons that do the main work, below them address bar, where we can navigate through folders and drives, and even lower we see files and folders that are located at the address selected above.

But in reality, this window is rarely used when creating archives. Almost always used Explorer context menu. Let's look at this process in more detail.

We decide on the information that we will pack into the archive. Right-click on the file or folder with files. In the context menu that opens, find the items “ 7-Zip – Add to archive».

In the window that opens, you need to make settings; let’s look at what’s there. Well, the very first thing is the name of the archive, set it or leave it as default if it suits us. In the drop-down list of the Archive format parameter, you need to select the format in which the files will be packed - 7z, ZIP, TAR or another of the proposed ones. The most commonly used are ZIP and 7z. The Compression level parameter, I think, is clear; the higher it is, the less the output archive will weigh, but the slower the compression will be. Almost at the very bottom we can specify the size of each file if we want to split it into volumes. On the right in the Options parameter there is an item “Create SFX archive". You need to check this box if you want a self-extracting archive to be created that will not require installed archivers on your computer for unzipping. I would like to note that when choosing, for example, a format ZIP archive, this function will not be available. Just below there is an Encryption option that will help protect your archive by creating a password for it. In this case, unpacking the archive will only be possible when you enter correct password. When everything is configured, click “OK” to start creating the archive.

In the picture below I have noted everything we have covered:

When creating archives in 7z format, I recommend creating SFX archives, since 7-Zip program Many people do not have it installed and may have problems when unpacking. A self-extracting archive does not need any programs. So take that into account.

7-Zip – world famous free archiver with free source code. The utility is compatible with almost all known archive formats. Plus, it has a built-in manager as a convenient shell. Command line control is also provided.

The manager has a file testing function. When activated, the number of files and the total size of the archive (in original and compressed states) are displayed. The number of errors found is also shown if the file suddenly turns out to be damaged. In this case, the user will not be able to open the archive, but it can be restored using or similar programs. But some zip archives cannot be opened due to incorrect headers (incorrect file encoding). In this case, it is better to use or.

The program is very easy to use. It is not necessary to run it to unpack or pack a file - just right-click on the required file and select the desired action.

7-Zip has already stood the test of time: developers continue to work on improving the utility for more than 15 years. During this time, the archiver gained wide popularity and became one of the most useful programs for various platforms.
