Copernic Desktop Search (CDS) brings the power of a sophisticated, yet easy-to-use search engine right to your PC and allows you instantly to search files, emails, and email attachments stored anywhere on your PC hard drive. It executes sub-second searching of Microsoft Word, Excel, and PowerPoint files, Acrobat PDFs, and all popular music, picture and video formats. CDS also conducts a desktop search of your browser history, favorites, and contacts.

Keeping the index “fresh” is a key factor in any search experience, and CDS maintains the freshest search index in the industry. With Copernic's patent-pending “Instant Indexing™” technology, new and updated files are indexed the instant they are saved to disk (Windows XP/2000/NT only), and emails are indexed the instant they arrive (Outlook only). You can't get fresher than that!

CDS was designed to be the world's lightest and most efficient desktop search with respect to CPU utilization. Copernic's exclusive patent pending “Smart Indexing™” technology monitors user activity and indexes only during idle time, assuring that CDS will never slow down your computer.

CDS features an exclusive fault-tolerant desktop search index. This means that if, during the course of the year, your search index has grown to 50,000 documents, you won't wake up one morning and find that your entire index has been corrupted, or has crashed, forcing you to restart the whole indexing process from scratch. With Copernic's patent pending fault-tolerant technology, your entire PC will always be searchable whenever you want it to be.

CDS takes your search terms as you type and searches your entire hard drive. As you add more terms to your search, you see your search results narrowing down right before your eyes. As you scroll through the results list of files or emails, a preview is shown on the bottom of the screen. Just click “open” and the file or email opens using its original application. Nothing could be simpler!
