7-Zip is a file archiver with a high compression ratio. 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. 7-Zip works for Windows 7, Vista, XP, 2008, 2003, 2000, NT, ME, and 98. And there is a port of the command line version to Linux/Unix. Most of the source code is under the GNU LGPL license. The unRAR code is under a mixed license with GNU LGPL + unRAR restrictions. Check the license for details.
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 was very highly recommended to me, so I downloaded it. When I went to install it, the first thing I saw was a message that the publisher is unverified and did I want to proceed? well, these days if there is any question about security, you don't want to install something that gives you a warning like that. So I deleted it. Too bad. My friend said it is a great product and he does not know why it is giving that warning message. Feedback would be app[reciated. Please let me know if this will change soon.
THIS FUCKING BITCH CONTAINS THIS--------> Trojan.Lethic.Win32
Warning: October 2015 :: this install frigs with your browser home page and other things. Without asking.
Broke my computer's ability to download zip files. Almost like a virus: very difficult to remove after destroying your computer's settings (despite multiple attempts to uninstall). I've been struggling with this system for over a month, trying to get things back to normal and I still can't download a zip file as a zip file. Came here and created this account specifically to warn people to stay away.
DANGER: I have recently discovered that 7-zip has been transferring data over the internet. The Creator Igor Pavlov has not explained. This application first appeared on the internet December 7 2010. My concern is this. 1. Nearly impossible to remove. 2. Unexplained internet usage. 3. Russians have been having a hay-day with American personal pictures and videos and using them for entertainment that is believed to be stolen from people's computers. (in the recent news). Is there a connection? I am very concerned there is a connection. This very well could be a source of information that is taken from people's PCs and delivered right into the hands of people you don't want the to have. I do not side with the reviews here on this application at all. People need to understand that Free is NEVER Free. You have to pay something. Often it's your email address and get spam. Your costs for FREE stuff. Sometimes FREE stuff costs a lot more. This one seems to have a very high price. Consumer be warned.
