About what to open 7z

Now we will tell you what to open 7z. This format is often enough. About what he is, and what programs can interact with him, we'll talk.

What are we talking about?

Before proceeding to the question of what to open 7z, it should be said that this is a format for compressing materials. The basis for it is the LZMA compression mechanism. This technology assumes a high compression ratio, as well as the possibility of encryption. The format supports the names of Unicode, as well as large-sized materials. Initially, the extension was introduced by the programmer Igor Pavlov in the "7-Zip" archiver. Currently, there are many file compression programs that support the specified extension.

Before installing an archiver on a computer, you need to determine the most important of the functions that you want to see in it. A lot of programs for unpacking and compressing files now have good capabilities, even being free, but all of them can be conditionally divided into convenient and powerful. In this case, the "powerful" can be attributed to applications that have several algorithms for encryption and compression ratios. In addition, such software solutions are able to split the archive into a specified number of volumes, and also provide the user with compressed passwords if desired.

Ease

If you are wondering about what an extension of 7z is, than opening 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 software is ideal for users who create archives infrequently, but with an enviable periodicity unpacks the materials received from the Internet.

To facilitate these applications, their developers often deprive them of various additional settings, while extracting files can be done through the context menu of the explorer.

WinRAR power

First of all, the answer to the question, than to open 7z, carries the application WinRAR. This program is an archiver with many functions that involve unpacking, editing and processing of materials. A variety of file formats are supported.

The application is developed in versions for 64- and 32-bit Windows operating 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 conditionally free. In other words, after 40 days of operation, the application will aggressively offer to purchase a license. This acquisition unlocks user access to technical support and updates. However, even if there is no 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 clever 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 certain modes the length of the crypto key is 256 bits. Files of any sizes are supported.

The user sets the compression level of the selected files. To create a universal archive that can be run on platforms where there is no installed archiver, use the SFX (self-extracting archives) function.

Alternatives

To answer a question, than to open 7z, can and set of other programs. Among them it should be noted: ZipGenius, NX Free, JustZIPit, J7Z, TUGZip, PeaZip, IZArc, 7-Zip and WinZip. From now on, you know that the archive represents 7z, than to open it and how to work with it. There are many programs for recognizing this extension, the choice is yours.
