7-Zip is a Free software/open source file archiver designed originally for Microsoft Windows, and later made available to other computer operating systems. In the form of p7zip, the command-line version of 7-Zip has been ported to Unix-like systems such as GNU/Linux, BSD, and Mac OS X as well as AmigaOS. It is also compatible with DOS via either a DOS port, or by using the HX-DOS extender to run the Windows command-line version. 7-Zip operates primarily with the 7z archive format, as well as being able to read several other archive formats. In operation a user can use the command line (all systems), graphical user interface (Windows only) or seamless Windows shell environment methods of control. 7-Zip began in 2000 and is actively developed by Igor Pavlov. In contrast to the market-leading programs WinZip and WinRAR, which remain as proprietary competitors, 7-Zip is distributed under the terms of the GNU Lesser General Public License (LGPL) (with the RAR license restrictions), and as such is free software (providing it is not distributed with the non-free RAR code). 7-Zip was the winner of the SourceForge.net 2007 community choice awards for "Technical Design" and for "Best Project".

The UI is a bit klugy, but zips and unzips multiple formats seamlessly.
Have been using this extensively over the past few months and there is a marked improvement over WinZip - almost 20-30%. This becomes a big deal when you're transferring and storing large amounts of media.
The Pepsi Challenge - I have an images folder that totals 270MB
And the winner is...
Winzip 10 -> 91MB
WinRAR -> 85MB
7 Zip -> 60MB
Any doubters???
its simple, its powerful and its FREE. Don't spend time evaluating winzip and others - just go with 7-zip - you wont be disappointed.
This is the simplest and one of the most useful utilities I've used. 7-zip just reinforces the whole open source premise of building better products through collaboration...
7zip over the period of time has proven itself to be the best zipper and unzipper as well. Much faster and lighter than the fancy Winzip and WinRar, it is pretty simple in use. The corresponding 7zip file manager does a good job of displaying the archives but has to be seperately associated with them, manually.
The fact that 7zip upacks almost any archive format makes it the best amongst them all.
Had talked about 7zip some time back at my blog:
http://open-source.onestop.net/2005/01/7-zip.html
i completely reinstalled winxp on an old desktop i have at home -- i didn't have any backup disks of the free software that was previously installed so i lost my winzip app.
i downloaded 7-zip from sourceforge (i think)... i have since installed it on every machine that doesn't have a winzip installation..
why pay for a tool like winzip, when you can get something like it for free?
it's a wise investment.
I'm using it instead of Winrar for a long time now... Very very good open-source software !
