My boss wants me to run Wndows 7 buil-in zip compression but I am a believer that Winzip and WinRAR are better tools for zipping data. I feel that Windows 7 zip does not allow me to included muliple zip files into a singles zip like WinZIp or WinRAR can do. Also there is no encryption that you can put on Windows 7 zip files.
Can someone give me some compelling reasons besides the ones above that I can use to justify purchasing Winzip or WinRAR over using Windows 7 zip? Also, I am not sure what makes Winzip different from WinRAR if someone can answer that for me.
