7-Zip is my favorite archiving software. I have not had 1 single problem with this program and have been using it for years. 100% satisfied. I'm amazed that it's free "open source."
This is almost as good as (if not better than) WinZip and Winrar. And it's free/open-source. Make sure to download from THIS WEBSITE ONLY: there are many fake versions floating out there. In fact, almost every 7-Zip hit in Google (except this one) is fake, and loaded with malware.
