7 zip

We all know how crucial hard disk space is, especially for those people who are constantly on the go and who always bring their work with them. It can be a problem sometimes because the files they need to bring with them are bigger than their free space. Worry no more - 7-Zip is here to the rescue. 7-Zip is an open source software for file compression and archiving, and unlike others, it offers a high compression ratio - definitely perfect for those big files that need to be shrinked.
