7-Zip

If you don’t use 7-zip, now is the time to get it. I use this tool a lot and I openly support it (in fact, for the most part, it’s the only compression utility I use – a lot of files that you may come across to download on this site will be straight up .7z). You’ll need 7-Zip for Windows to extract those. Luckily most Linux users won’t need much of anything if you are using a modern distro.
