7-Zip features and benefits
Some of the features and benefits of using 7-Zip are:
It is free software with open source. You can use 7-Zip on any computer, including a computer in a commercial organization. You don't need to register or pay for 7-Zip.
It has strong AES-256 encryption in 7z and ZIP formats, which can protect your files from unauthorized access.
It has a self-extracting capability for 7z format, which means you can create an executable file that can extract itself without requiring any additional software.
It has integration with Windows Shell, which means you can right-click on any file or folder and access 7-Zip functions from the context menu.
It has a powerful file manager and command line version, which give you more control and flexibility over your archives.
It has localizations for 87 languages, which make it more user-friendly and accessible.
7-Zip supported formats and compression ratio
One of the main advantages of using 7-Zip is that it supports many different formats for packing and unpacking files. The table below shows some of the supported formats by 7-Zip:
Packing / unpackingUnpacking only
7z, XZ, BZIP2, GZIP, TAR, ZIP, WIMAPFS, AR, ARJ, CAB, CHM, CPIO, CramFS, DMG, EXT, FAT, GPT, HFS, IHEX, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, QCOW2, RAR, RPM, SquashFS, UDF, UEFI, VDI, VHD, VHDX, VMDK, XAR and Z
The most popular format used by 7-Zip is the 7z format. The 7z format has a high compression ratio that can be up to 70% better than the ZIP format. The compression ratio depends on the type of data used for the tests. For example, we compared 7-Zip with WinRAR using two file sets: Mozilla Firefox and Google Earth. The results are shown in the table below:
File set7-Zip sizeWinRAR sizeDifference
Mozilla Firefox23.2 MB30.6 MB-24.2%

Download 7-Zip from SourceForge
SourceForge is a website that hosts open source software projects. You can also download 7-Zip from SourceForge if you prefer. The advantage of downloading from SourceForge is that you can choose from different mirrors (servers) that may be closer to your location and faster to download from.
To download 7-Zip from SourceForge, follow these steps:

Choose the right version of 7-Zip for your system
Before you download 7-Zip, you need to make sure that you choose the right version for your system. There are two main factors that determine which version of 7-Zip you should download: your system architecture and your preferred format.
Your system architecture refers to whether your computer has a 32-bit or a 64-bit processor. A 32-bit processor can only handle up to 4 GB of RAM, while a 64-bit processor can handle more than that. A 64-bit processor can also run faster and more efficiently than a 32-bit processor.
To check your system architecture on Windows, follow these steps:
Right-click on the Start menu and select "System".
A window will open with information about your system. Look for the section that says "System type". It will tell you whether your system is 32-bit or 64-bit.
Choose the version of 7-Zip that matches your system type. For example, if your system is 64-bit, download the 64-bit version of 7-Zip.
Your preferred format refers to whether you want to download the exe or the msi file. The exe file is an executable file that can run directly on your computer. The msi file is a Windows Installer file that can install 7-Zip on your computer. The exe file is usually smaller and faster to download, while the msi file is more secure and easier to uninstall.
To choose your preferred format, follow these steps:
Decide whether you want to download the exe or the msi file. If you are not sure, we recommend downloading the exe file as it is more convenient and simple.
Choose the download link that matches your preferred format. For example, if you want to download the exe file, click on the link that ends with ".exe".

Click on the Start menu and look for the 7-Zip folder. If you created a Start Menu folder during the installation, you will find it there. Otherwise, you will find it under All Programs.
Click on the 7-Zip folder and then click on 7-Zip File Manager. Alternatively, you can double-click on the desktop icon if you created one during the installation.
A window will open with two panels: the left panel shows your drives and folders, and the right panel shows the files and subfolders in the selected folder. You can use the toolbar buttons or the menu bar to access various functions of 7-Zip File Manager.
Create a new archive with 7-Zip
To create a new archive with 7-Zip, follow these steps:
Open 7-Zip File Manager and navigate to the folder where you want to create the archive.
Select the files and folders that you want to include in the archive. You can use Ctrl+click or Shift+click to select multiple items.
Click on the Add button on the toolbar or go to File > Add to archive. A window will open with various options for creating the archive.
Choose a name and a location for the archive. You can use the Browse button to select a different folder or drive.
Choose a format for the archive. The default format is 7z, but you can also choose ZIP, TAR, WIM, or any other format supported by 7-Zip.
Choose a compression level for the archive. The default level is Normal, but you can also choose Fast, Fastest, Ultra, Maximum, or Store (no compression).
Choose a compression method for the archive. The default method is LZMA2, but you can also choose LZMA, PPMd, BZip2, or Deflate.
Choose a dictionary size for the archive. The default size is 64 MB, but you can also choose from 16 KB to 1 GB. The larger the dictionary size, the better the compression ratio, but also the longer the compression time.
Choose a word size for the archive. The default size is 32, but you can also choose from 8 to 273. The larger the word size, the better the compression ratio, but also the longer the compression time.
Choose a solid block size for the archive. The default size is Solid, which means that all files are compressed as a single block. You can also choose Non-solid or any other size from 64 KB to 4 GB. The smaller the block size, the faster the extraction time, but also the lower the compression ratio.
Choose an encryption method for the archive. The default method is ZipCrypto, but you can also choose AES-256 if you want stronger encryption. You will need to enter a password and confirm it.
Choose any other options that you want for your archive, such as splitting into volumes, creating a self-extracting archive, adding comments, etc.

Choose any other options that you want for your extraction, such as preserving paths, overwriting existing files, testing integrity, etc.
Click OK when you are ready to extract your archive. The extraction process will start and may take some time depending on your archive size and format.
Once the extraction is complete, you will see your extracted files in the selected location. You can open them with your preferred software or delete them if you don't need them anymore.
Integrate 7-Zip with Windows Shell
