An application for opening 7Z files. How to open file.7z? How to unpack a multi-volume archive

One of the most qualitative formats of archiving according to the compression ratio is 7z, which this direction May compete even with RAR. Let's find out, with what kind of programs you can open and unpack the archives 7z.

Almost all modern archivers can know if not creating objects 7z, then, in any case, browse them and unpack them. Let us dwell on the actions algorithm for viewing the contents and unzip the specified format in the most popular archival programs.

Method 1: 7-Zip

Let's start our description from the 7-ZIP program, for which the 7Z is declared "native" format. It is the developers of this program that created the format studied in this lesson.


If the 7-ZIP program is installed on the default computer for manipulations with 7z format, then it will be enough to open the contents by being in Conductor windowsClick twice LKM. By the name of the archive.

If you need to perform unzip, then the algorithm of action in 7-zip will be somewhat different.


The 7Z object is unzipped into the folder that is indicated above.

If the user wants to unpack not the entire archived object, but separate filesThis action algorithm changes slightly.


Method 2: WinRar

Popular winrar archiver also works with 7z, although for him this format And it is not "native."


As you can see, the actions algorithm for viewing the contents are very similar to the one that has been used when working with 7-zip.

Now let's find out how to unpack 7z in Viryrr. There are several methods for performing this procedure.


There is also the possibility of instant unacceptable without specifying any additional settings, including the path. In this case, the extraction will be executed in the same directory where the archived object is placed. To do this, click 7Z PKM. and select "Extract without confirmation". You can replace this manipulation with a combination Alt + W. After selecting an object. All items will immediately be unzipped.

If you want to unzip not the entire archive, but certain files, then the actions algorithm is almost exactly the same as for the unimbranch object as a whole. To do this, go inside the 7Z object via the VIRRAR interface and select the necessary elements. Then, according to how you want to unpack, make one of the Lenses:

  • Click "Extract ...";
  • Choose "Extract to the specified folder" in the context list;
  • Dial Alt + E.;
  • In the context list, select "Extract without confirmation";
  • Dial Alt + W..

Everything next steps Conduct adhering to the same algorithm as to unzip the archive as a whole. Specified files will be retrieved either in the current directory or to the one you specify.

Method 3: IZARC

Manipulate 7z files can also be as small and convenient IZARC utility.


To retrieve content, you need to do the following manipulation.


In IZARC, there is also the possibility of unpacking individual elements of the archived object.


Method 4: Hamster Free Zip Archiver

Another method Open 7Z - Use Hamster Free Zip Archiver.


You can enter differently.


The marked files will be removed in the designated directory.

You can also execute the archive as a whole.


There is a faster option to unpack 7z completely.


Method 5: Total Commander

In addition to archivers, viewing and unpacking content 7Z can be performed using specific file managers. One of these programs is Total Commander.


In order to unzip the entire archive, the following manipulations should be performed.


If you want to extract only certain files, then act differently.


As you can see, viewing and unpacking archives 7z supports a rather large list of modern archivers. We only indicated the most famous of these applications. The same task can be solved using certain file managers, in particular Total Commander.

7-ZIP - free file archiver offering a high compression ratio. The program is an analogue of popular WinRAR, but it spreads absolutely free.

Archiver 7-zip is easy and easy to use. Its intuitive and convenient interface transferred to 60 languages, which makes the program quite universal. One of the main advantages is 7-zipa is the presence of a powerful archiver file Manager, plugin for Far Manager.. The program can be embedded in the conductor "Windows" and self-expanding archives 7z.

Among other things, the 7-zip has a high compression ratio and works with files 7z, Zip, BZIP2, GZIP, TAR (Packs / Unpacks) and archives of RAR, RPM, ARJ, LZH, CAB, Z, CPIO, CHM, DEB ( Unpacks).

The 7-ZIP program supports AES 256-bit encryption, is capable of working with such popular archives as RAR (including RAR3 and CAB), ZIP.

The main characteristics of the 7-zip archiver:

  • the program supports the following formats: 7z, Zip, MSI, CAB, RPM, Z, DEB, LZH, NSIS, RAR, ARJ, CHM, WIM, GZIP, BZIP2, CPIO, ISO, TAR and RPM;
  • 7-zip offers a very high degree of compression in 7z format;
  • working with Zip Gzip formats, get a compression ratio of 2-10 percent higher than in Winzip and PKZip;
  • creation for 7Z format self-extracting archives;
  • encryption archives;
  • the presence of a built-in file manager;
  • integration into the shell operating system Windows;
  • availability of a plug-in for Far Manager and Total Commander programs;
  • powerful command line support;
  • multilingual interface includes Russian.

Annex 7-Zip is a serious world player of archivers, whose main goat is your own LZMA algorithm, "squeezing" files in the 7Z format. From its "Competitors' Colleagues" WinRar and Winzip This free archiver is characterized by slower work, while the "reduced" speed is easily compensated by a much higher degree of compression. As a result, the 7-zip is wonderful to work with the giant files, and this "archiver-strongman" can work by 30% more efficiently of its faster competitors.

At the same time, 7-ZIP is not as safe as WinZip or WinRAR, due to the lack of a virus scanner, but this program has no less opportunity. 7-ZIP works with a large number of archived formats and contains such convenient tools as update and separation modes (Splitting).

I think 7-zip download free of charge Each computer user, Taka, as the program is really indispensable and still has free status.

In this article, I will teach you to unpack the archives. It is very simple.

The archive is one file with a set of others to reduce the place occupied by them.

They are very effective to use if access to information is needed very rarely and the space occupied Veliko.

Usually they have extensions:

Well, others. Extensions are a lot. These are the most popular.

The archive can be compressed and this seriously saves free space. They are also often used to transfer a large number of information. This is especially useful if you need to transmit it via the Internet, and the traffic limit is limited.

Even if you put a password for the archive, this will ensure reliable information protection. And for this, you will just need skills to work with them.

Additionally, I want to say that it is not necessary to fully remove all files. You can get only necessary. It is very convenient than to dig in the whole pile of information.

To unpack Zip, you can do with Windows tools. In other cases you have to use the archiver.

Archiver - program to work with archives.

In the example, I will use the 2 most popular and universal:

  1. WinRAR is conditionally free.
  2. 7Zip is completely free.

It is worth noting that the unpacking creates a copy of the files in the open form and therefore you can safely delete the unpacked archive ( not always like this). Now I will show how to do it.

You can see this instruction in both the article and in the video. In it, everything is very detailed.

Unpack Zip using Windows Explorer

Windows Explorer allows you to unpack the archives with the zip extension. To do this, click on it right mouse button. In the appearance context menu, Select "Extract everything ..." as in the picture below.

Then the window will appear. In it, specify the path where to unpack and proceed to remove.

This method works only with zip format. For other formats, you must use the third-party archiver.

Unpack with 7-zip

Download free program 7-zip. For a 32-bit bit or for a 64-bit bit. It will allow you to quickly and easily unpack various formats of archives. Look at the discharge in the characteristics of your computer.

After installing it, the 7-Zip tab appears in your context menu. Go to it and select "Unpack" as in the image below.

In the window, specify the extraction path ( default his location).

Files will appear in the place you specified.

WinRar

WinRAR is very convenient for the program and works with all extensions. It is paid, but has a free trial period of 40 days. Then you will constantly show the window about buying a license. In general, it can be used for free.

Download it from the official site and install.

Unpacking in it occurs just as in 7-zip. They differ in convenience and additional features.

As you can see on the left there are several additional features Simplifying work. Confirm your extraction and go to unpacked files.

Unpacking a damaged archive

When unpacking, an error "Archive is damaged" occurs and to extract files, you will need to use the features of WinRar. Such an error may occur even if 1 kilobyte information is damaged, and therefore it makes sense to extract and see which files remained workers.

When removing, check the box next to "Do not delete files extracted with errors" and it is unpackled. Look, it is on the left in the image above.

Note that in this case, not all files will be operational.

Unpacking the archive consisting of several volumes

To do this, it is enough to collect all the volumes in one folder and unpack the first volume. Other on the chain are unpackled behind it.

Please note that all volumes must be present and it follows the same program-archiver to which they were made. Then everything will go well.

Check out the example in the picture below.

They look like this, an extension with a sequence number is added at the end. Otherwise, they do not differ from ordinary.

I hope you managed to extract the files you need and you can easily do it in the future. If you have questions - ask in the comments.

What do you unpack the archives?

Poll Options Are Limited Because JavaScript is Disabled in Your Browser.

The most common problem, due to which users cannot open this file, is an incorrectly assigned program. To fix it in Windows, you need to right-click on the file, in the context menu, bring the mouse to "Open Using" item, and select the Select Program item drop-down menu. As a result, you will see a list. installed programs On your computer, and you can choose the appropriate. We also recommend that you check the box opposite the item "Use this application for all 7z files".

Another problem with which our users also occur quite often - the 7z file is damaged. Such a situation may arise in cases of cases. For example: the file was downloaded not fully as a result server errorsThe file was damaged initially, etc. To eliminate this problem, use one of the recommendations:

  • Try to find the desired file. In another source on the Internet. You may be lucky to find a more suitable version. Google search example: "File filetype: 7z". Just replace the word "file" to the name you need;
  • Ask you to send you the source file again, it may have been damaged during transmission;

7Z Archive file format

Released in 1999 developer Igor Pavlov based on a 7-zip program, 7Z format is able to support different types Algorithms for compressing data, encryption and pre-processing. It is considered to be "obsolescence protected", since the format is maintained by a large number of new archivers. Currently, 7z is an open source expansion available for public use since 2008. Compression methods that support 7Z, LZMA, PPMD, BCJ, BZIP2 and Deflate files are supported. An open architecture allows you to put compression, conversion and encryption methods. This type of files is used to store and send / obtain particular large files or their groups. Do you want to use this universal archive file yourself? Try here.

Technical information about the files 7z

Files up to 16 billion GB (16 exbibate) can be compressed using a 7-zip program with a sufficiently large compression coefficient, as well as use the AES-256 encryption method. Dimensions of dictionaries can be up to 4 GB. In this case, the compression speed is up to 1 MB / s, and the velocity speed is up to 20 MB / s (in the case of using processors with clock frequency 2 GHz). The length of the unpacking code is 5 kb. 7z files can be multi-volume archives that can be converted into one file after the transfer of the archive along the volume. It is worth noting that the 7Z format does not support the storage of access rights file Systems (ACL UNIX or NTFG), i.e. Using 7Z format for reserve copy And archiving may be problematic due to the availability of security bypass.
