Copernic Desktop Search - 2.3 build 18

Copernic Desktop Search brings a search engine right to your PC and allows you to instantly search files, e-mails, and e-mail attachments stored anywhere on your PC hard drive. The application executes subsecond searching of Microsoft Word, Excel, and PowerPoint files, Acrobat PDFs, all popular music, picture, and video formats, contacts, the browser history, and Favorites. It features a seamlessly integrated previewer that instantly provides you with a view of the file or e-mail you're looking for. The previewer highlights all search terms and automatically scrolls to the first use of these terms in a document, eliminating the frustration of having to sort through endless text to pinpoint specific words.

Version 2.3 build 18 added default desktop search integration options for Windows Vista SP1.
