7-Zip is an open source file archiver. You may ask why not Winzip and WinRAR? Both Winzip and WinRAR are great file archivers and extractors. But neither of them are free. 7-Zip on the other hand is completely free, extremely small and supports a great variety of file formats. Download and installation is quick and painless. It resides in the user’s right click menu – if you need to use 7-Zip just right click on the file or folder. For more info check the 7-Zip Wikipedia page.
