7-Zip is a file archiver with a high compression ratio and 7-Zip is open source software that supports (reads and writes) many poplar archive formats (zip, rar, 7zip, iso). The current recommended version is 7-Zip 9.22 beta. http://sourceforge.net/projects/sevenzip/forums/forum/45797/topic/4492007 7-Zip began in 1999 and is actively developed by Igor Pavlov. Unfortunately, the icons that come with the installation file are old looking. Good People came up with a method of changing them after installing 7zip. I found that this method works like a charm: http://thatnetsite.com/2010/06/replacement-icons-for-7-zip-ver3/ I made a batch of svg files and turned them into ICO files (I used IcoFX - The Free Icon Editor to convert the PNG to ICO). Enjoy the SVG.
