After having tried HotBot’s toolbar and Blinkx to no avail, I’ve finally come accross a free tool that will index my hard disks usefully.

May I happilly refer you to: Copernic’s desktop search for Windows. Granted, it takes some time before those big modern hard disks have been indexed. But it works.

And it has a preview screen. And it doesn’t need a browser. And it recognizes rtf’s.
