If Google Desktop isn't doing the trick for you, check out Copernic's Desktop Search Professional. The company just released an update to the program, which is aimed at small business and worker bees with an organizational bent. The latest version fixes a handful of bugs and adds high capacity indexing functionality. Other noteworthy features include the ability to search any file on your hard drive or network drive as well as save your most frequent searches. You can also export your list of results in an HTML file; select specific files and e-mail folders to index; control computer resources usage when indexing documents; and get desktop and Web results with a single search. In addition, the download comes with handy search toolbars for both your desktop and browser.
Copernic Desktop Search Professional will set you back $49.95, but you can test it out for 30 days before committing to the purchase. Anyone who doesn't need all the features offered by the Professional version of of the software can still download Copernic Desktop Search Home for free. However, the publisher did not update this particular program today.
