Copernic Desktop Search - The Search Engine for Your PC

"Easily search your entire hard drive in less than a second to pinpoint the right file, e-mail, music or pictures."

Google is behind on this one! I have tried both and found CDS preferable. In my case, it has to do with what drives the application will allow you to search, but there are more differences between the apps. Try it for yourself and see what you think. It is a free download and installed easily and trouble-free on my system.
