7-Zip Portable is the portable version of the awesome free file extraction app,
Being portable means that you'll be able to use this high-ratio compressor and extractor to manage files wherever you are - even if you're on the go or using 7-Zip Portable on a computer that's not yours. Given the utility of the app, it's probably a good idea to keep it on a pendrive so you can have access to it no matter where you are.
7-Zip Portable is one of many file compression apps, but it stands out because it can fit a lot of information into a small space - in other words, it can make large files much, much more manageable. You can use it either for compressing large files you own, or for opening files that other users have compressed. Either way, 7-Zip Portable couldn't be easier to use.
The app's interface is plain, but very self-explanatory and easy to use. It's integrated into the context menu, which means that to compress or extract a file, you only need to right-click. Double clicking on a compressed archive will extract it, and, of course, you can extract and compress via 7-Zip Portable's main interface and the buttons in the top bar.
Being open source and thoughtfully developed, 7-Zip Portable also has a number of nice features that don't always come as standard. Data nerds will love the benchmarking feature, while everybody should appreciate the test option (for making sure files aren't corrupted), excellent hotkeys and general selection of very user-friendly options.
Give 7-Zip Portable a try. If you're looking for portable, free and, above all, outstanding file compression and extraction, it's probably the app for you.
