Yahoo releases beta version of PC search software available at no charge through the site http://desktop.yahoo.com. Yahoo's application uses X1 Technologies Inc.'s search engine to index emails, attachments, documents, music, images, videos and other content. X1 claims to scan more than 200 different file types, including Outlook email, PDF, HTML, text, ZIP, MP3 and Word, Excel and PowerPoint documents. Yahoo Desktop Search currently only works with computers running Microsoft's Internet Explorer browser on Windows XP and Windows 2000 operating systems. I found it better than Ask Jeeves,Microsoft and Google desktop search in terms of customization, speed, instant preview and various types of files it searches.
