Files with z extension. What is the Z file extension? Quiz: What file extension is the bitmap type
This format is quite common. We will talk about what it is, as well as what programs can interact with it.
What are we talking about?
Before moving on to the question of how to open 7z, it should be said that this is a material compression format. It is based on the LZMA compression mechanism. This technology assumes high as well as the possibility of encryption. The format supports Unicode names as well as large material. Initially, the extension was introduced by programmer Igor Pavlov in the 7-Zip archiver. Currently, there are many file compression programs that support the specified extension.
Before installing one or another archiver on a computer, you need to determine the most important of the functions that you want to see in it. Many programs for unpacking and compressing files now have good features, even being free, but all of them can be divided into convenient and powerful ones. At the same time, applications that have several compression levels can be classified as “powerful”. In addition, such software solutions can split the archive into a specified number of volumes, as well as supply compressed materials with a password if the user wishes.
Ease
If you are wondering what the 7z extension is, how to open it and how to work with it, more “convenient” solutions can help you. They are optimized to achieve the fastest processing of archives. This type of program is ideal for users who create archives infrequently, but unpack materials received from the Internet with enviable frequency.
To make these applications easier, their developers often deprive them of various additional settings, while extracting files can be done through the explorer context menu.
The Power of WinRAR
First of all, the answer to the question of how to open 7z is the WinRAR application. This program is an archiver with many functions that involve unpacking, editing and processing materials. Various file formats are supported.
The application is developed in versions for 64- and 32-bit operating systems. Windows systems, and also has special editions for many popular platforms: FreeBSD, Android, Windows Mobile, Os X, Linux. If we talk about the version for Windows, it should be noted that it is shareware. In other words, after 40 days of operation, the application will persistently offer to purchase a license. Such a purchase unlocks the user's access to technical support and updates. However, even in the absence of a license, the archiver will continue to work properly. In order to create an archive, the program can use its own RAR format, as well as the familiar ZIP.
The application has a smart analyzer that can independently determine the optimal sequence and compression technology. This software solution has its own archive security key. Each archive is accompanied by an electronic signature and a cryptographic protection key, the length of which is 128 bits. If we talk about the latest versions of the archiver, in some modes the length of the crypto-key is 256 bits. Files of any size are supported.
The user sets the degree of compression of the selected files. To create a universal archive that can be run on platforms that do not have an archiver installed, use the SFX (Self-Extracting Archives) feature.
Alternatives
Many other programs can answer the question of how to open 7z. Among them, it should be noted: ZipGenius, NX Free, JustZIPit, J7Z, TUGZip, PeaZip, IZArc, 7-Zip and WinZip. From now on, you know what a 7z archive is, how to open it and how to work with it. There are many programs for recognizing this extension, the choice is yours.
One of the highest quality archiving formats in terms of compression ratio is 7z, which can even compete with RAR in this direction. Let's find out with which programs you can open and unpack 7z archives.
Almost all modern archivers can, if not create 7z objects, then, in any case, view them and unpack them. Let's dwell on the algorithm of actions for viewing the content and unzipping the specified format in the most popular archiving programs.
Method 1: 7-Zip
Let's start our description with the 7-Zip program, for which 7z is declared as a "native" format. It was the developers of this program who created the format studied in this lesson.
If the 7-Zip program is installed on the computer by default for manipulating the 7z format, then it will be enough to open the content simply by being in Windows Explorer, double click paintwork by archive name.
If you need to unzip, then the algorithm of actions in 7-Zip will be somewhat different.
The 7z object is unzipped into the folder indicated above.
If the user wants to unpack not the entire archived object, but individual files, then the algorithm of actions changes slightly.
Method 2: WinRAR
The popular WinRAR archiver also works with 7z, although this format is not "native" for it.
As you can see, the algorithm of actions for viewing content is very similar to the one that was used when working with 7-Zip.
Now let's find out how to unpack 7z in WinRAR. There are several methods for performing this procedure.
There is also the possibility of instant unzipping without specifying any additional settings, including the path. In this case, the extraction will be performed in the same directory where the archived object is located. To do this, press 7z PKM and select "Extract without confirmation". You can replace this manipulation with a combination Alt+W after selecting an object. All items will be immediately unzipped.
If you want to unzip not the entire archive, but certain files, then the algorithm of actions is almost exactly the same as for unzipping the object as a whole. To do this, go inside the 7z object through the WinRAR interface and select the necessary elements. Then, depending on how you want to unpack, do one of the following:
- Click "Extract...";
- Select "Extract to specified folder" in the context list;
- Dial Alt+E;
- In the context list, select "Extract without confirmation";
- Dial Alt+W.
Perform all further actions following the same algorithm as for unzipping the archive as a whole. The specified files will be extracted to either the current directory or the one you specify.
Method 3: IZArc
A small and handy IZArc utility can also manipulate 7z files.
To extract the content, you need to do the following manipulation.
IZArc also has the ability to unpack individual elements of an archived object.
Method 4: Hamster Free ZIP Archiver
Another method to open 7z is to use the Hamster Free ZIP Archiver.
You can do it differently.
The marked files will be extracted to the designated directory.
You can also unzip the archive as a whole.
There is a faster option to unpack 7z completely.
Method 5: Total Commander
In addition to archivers, viewing and extracting 7z content can be done using certain file managers. One such program is Total Commander.
In order to unzip the entire archive, perform the following manipulations.
If you want to extract only certain files, then we act differently.
As you can see, viewing and unpacking 7z archives supports a fairly large list of modern archivers. We have only indicated the most famous of these applications. The same task can be solved with the help of certain file managers, in particular Total Commander.
- The extension (format) is the characters at the end of the file after the last dot.- The computer determines the file type precisely by extension.
- By default, Windows does not show filename extensions.
- Some characters cannot be used in the file name and extension.
- Not all formats are related to the same program.
- Below are all the programs with which you can open the 7Z file.

If your computer has antivirus program Can scan all files on the computer, as well as each file individually. You can scan any file by clicking right click by clicking on the file and selecting the appropriate option to perform a virus scan on the file.
For example, in this figure, file my-file.z, then you need to right-click on this file, and in the file menu select the option "scan with AVG". Selecting this option will open AVG Antivirus, which will scan the given file for viruses.
Sometimes an error can result from incorrect installation software , which may be due to a problem that occurred during the installation process. It may interfere with your operating system associate your Z file with the correct software application, influencing the so-called "file extension associations".
Sometimes simple reinstalling 7-Zip may solve your problem by properly linking Z to 7-Zip. In other cases, file association problems may result from bad software programming developer, and you may need to contact the developer for further assistance.
Advice: Try updating 7-Zip to latest version to make sure the latest patches and updates are installed.
This may seem too obvious, but often the Z file itself may be causing the problem. If you received a file via an attachment Email or downloaded it from a website and the download process was interrupted (such as a power outage or other reason), the file may be corrupted. If possible, try getting a fresh copy of the Z file and try opening it again.
Carefully: A corrupted file may cause collateral damage to a previous or existing malware on your PC, so it is very important that you have an up-to-date antivirus running on your computer at all times.
If your Z file associated with the hardware on your computer to open the file you may need update device drivers associated with this equipment.
This problem usually associated with media file types, which depend on the successful opening of the hardware inside the computer, for example, sound card or video card. For example, if you are trying to open an audio file but cannot open it, you may need to update sound card drivers.
Advice: If when you try to open a Z file you get .SYS file related error message, the problem could probably be associated with corrupted or outdated device drivers that need to be updated. This process can be facilitated by using driver update software such as DriverDoc.
If the steps didn't solve the problem and you are still having problems opening Z files, this may be due to lack of available system resources. Some versions of Z files may require a significant amount of resources (eg. memory/RAM, processing power) to open properly on your computer. This problem is quite common if you are using fairly old computer hardware and a much newer operating system at the same time.
This problem can occur when the computer is having a hard time completing a task because operating system(and other services running in background) can consume too many resources to open Z file. Try closing all applications on your PC before opening Unix Compressed File. By freeing up all available resources on your computer, you will ensure the best conditions for trying to open the Z file.
If you completed all the above steps and your Z file still won't open, you may need to run hardware upgrade. In most cases, even with older hardware versions, the processing power can still be more than enough for most user applications (unless you're doing a lot of CPU-intensive work like 3D rendering, financial/science modeling, or intense media work) . Thus, it is likely that your computer does not have enough memory(more commonly referred to as "RAM", or RAM) to perform the file open task.
Every year the number of various file formats increases, it is almost impossible to keep track of all these innovations. When downloading another program or, perhaps, some information from the Internet, you may encounter files in the 7z format. About what this format is and how to read it, read this article.
The 7z format appeared quite a long time ago, back in 1999. It belongs to a program with almost the same name - 7zip. As you might guess, this program is a file archiver. This software was developed by Russian programmer Igor Pavlov. The main distinguishing feature of the program is a high compression ratio, which you can choose yourself.
The best way to read files with the 7z extension is, of course, the original 7zip program. Fortunately, for users it is completely free and is in the public domain. If you consider yourself a real programmer, then another good news for you lies in the fact that the source code is open. You can download the program on the official website by clicking on the link:
How to open 7z
How to download the program? Follow the link above, at the very top of the window you will see a small green table. In the first column, by clicking on Download, you will download .exe file, which is designed to install the archiver on 86-bit systems (32-bit). Below is a link to the installer for 64-bit Windows systems. 
After installation, you can try to open files with the 7z extension. The operating system must carry out the association with the program on its own. If this does not happen, then right-click on the file, select the line that says "Open with" and select the 7zip archiver.
Working in the 7zip archiver is very comfortable and simple, the interface speaks for itself. There are not so many buttons, special knowledge of English is not required, only a minimum is needed. To open the 7zip archive, you can either transfer the file to the workspace or specify the path to it.
There are other archivers and file managers, which can recognize the .7z extension. These include the following software: WinRar, Corel WinZip, PeaZip, PowerArchiver, TotalCommander, MultiCommander and other programs. Some of the programs on this list are paid, some are freely available. If you do not want to litter your computer with numerous archiving programs of the same type, then we recommend using the WinRar program, which recognizes a huge number of different formats.
