7-Zip at a GlanceAfter you effortlessly download and launch 7-Zip, you’ll quickly discover its simple and easy to navigate interface. The main toolbar contains 7-Zip’s most used features and there are several menus that allow you to dig deeper within. For example, the Extract button lets you easily browse for or accept the default destination directory for your file, while the View menu contains a Folder History, and the Favorites menu lets you save up to ten folders. 7-Zip also integrates with the Windows Explorer menus, displaying archive files as folders and providing a toolbar with drag-and-drop functions. You can also alternate between a single or dual-pane view.
Product Details7-Zip offers several features that make it one of the best compression software options around. For example:
- Open architecture—The source code uses the GNU LGPL license, while the unRAR code is under a mixed license with GNU LGPL + unRAR restrictions.
- High compression ratio—Using its own 7z format with LZMA and LZMA2 compression, 7-Zip’s compression ratio is up to 40% higher than its peers. For ZIP and GZIP formats, 7-Zip provides a compression ratio that is 2-10% better than PKZip and WinZip.
- Strong AES-256 encryption—This includes both password protection of files and encryption of file names.
- Ability to use may compression, conversion, or encryption methods—For example 7-Zip:
- Supports packing and unpacking for 7z, XZ, BZIP2, GZIP, TAR, ZIP, and WIM.
- Supports unpacking only for ARJ, CAB, CHM, CPIO, CramFS, DEB, DMG, FAT, HFS, ISO, LZH, LZMA, MBR, MSI, NSIS, NTFS, RAR, RPM, SquashFS, UDF, VHD, WIM, XAR, and Z.
- Supports a self-extracting capability for 7z format.
- Integrates with Windows Shell—Using its menu options, you can integrate 7-Zip to the Windows Shell menu.
- Powerful file manager and command line versions—There’s also a plugin for FAR Manager.
- Localizations for 79 languages—This kind of support is why 7-Zip is the world’s favorite free compression software.
|7-Zip is easy to download and use, it opens and compresses most everything, and is has a Windows shell extension.||The interface is a little sparse and so are the instructions, but the program works like a charm anyway.|

7-Zip is an awesome program to find and run things by. It merges Explorer and Finder. It can open nearly all folders of every type. It needs to find a way to open .text files, just as other hidden content. It would also be great to configure selected files with Notepad++. Besides that, it does awesome.
Easy to use unpacker. The best unarchiver after legendary WinRAR.
I like 7-zip a lot, but here's a feature request: I just zipped a big folder, and the process used up 98% of my dual-quad-core CPU time, bringing the rest of my laptop to a screeching halt. I don't see any way of throttling the process, so that would be helpful. Thanks!
Everything is great. But the user interface could use some improvements.
I have been using this program for a long time and greatly appreciate its new ability to handle symbolic links in Windows as I often use them and wish to back up my files to servers in other countries which means I want to compress them first. 7-Zip also seems to compress and decompress much faster than before which is helpful when you are compressing 45,000 files at once! (I think the fact that it doesn't list every one of these files as it compresses them is the big help. It just lists some of them, something like one file per second is listed.)
