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.|

True the compression ratio is great but.. this app has major issues that havent been addressed in years and are blatently obvious to any windows user. The compression thread priority appears to be set at the same level as the window thread making it unresponsive or ludicrously slow. FYI the gui should always be > or at least = to the packing thread. The gui looks as if it was written by adding toolbar buttons to a msvc6.0 template. Ie. Bad. This compression app deserves a better gui if it is ever to be as useable as winrar/winzip. Try winrars shell extentions for an example of user configured usablity. Please stop squezzing 0.00021blah% more compession out of it and deal with the UI please.also while it gets slightly better compression than winrar it is MUCH slower at packing. Id Love to love it but i dont. Sorry.
Stable, reliable, fast and functional. However, it has some neglected flaws: -no support for UAC -drag 'n' drop causes files to extracted and then copied, which is very slow -Doesn't have a function for running an installer from an archive
Excellent Software. @ download-ardamax-keylogger-withcrack.blogspot.com Download Ardamax Keylogger 4.1 with crack free and hack today facebook,twitter etc but don't mis-use it.
7Zip does not handle Windows junctions or symbolic links at all. I see this has been reported in your bug list years ago, but nothing has been done about it.
