7-Zip 9.33 Alpha - Neowin
That's vital if you need to e-mail sensitive data, because the .zip format's standard password protection (the only kind Windows supports) is easy to crack. But with 7-Zip, you can share truly-secure data with people who use WinZip, PKZip, WinRar , PowerArchiver, and other programs. And if they use none of those programs and don't want to spend money, you can tell them to http://7-zipdownload.us get 7-Zip. 7-Zip also allows you to compress and e-mail files in one easy step. Just right-click a file or files in Windows Explorer and select 7-Zip then Compress and email. It even has its own compression format, although I recommend sticking to .zip for compatibility purposes. This isn't to say that 7-Zip will satisfy every WinZip fan. It can't compress a .zip into an .exe. And the user interface is plain, dull, and unattractive. It can also be intimidating, offering options that most users should never have to think about.
