Index.dat files are windows system files on windows which records every web site you visit with internet explorer. These files are hidden on your computer that contain all of the Web sites that you have ever visited.
Every URL, and every Web page is listed there. Not only that but all of the email that has been sent or received through Outlook or Outlook Express is also being logged. Microsoft has not supplied an adequate explanation as to what these files are for or why they have been hidden so well.
