Another new feature available with Total Privacy 5.1 (and also available as a freeware utility) is a index.dat Viewer. What’s different about it is that it reads the index.dat files directly. This makes sure that what you see displayed by the program are the exact contents of the index.dat files.
What are Index.dat Files?
Index.dat are files hidden on your computer that contain all of the Web sites that you have ever visited. Every URL, cookies and browsing history is listed there. The file names and locations depend on what version of Internet Explorer you have. If you are running IE version 4.0 or above, the file name is “index.dat”.
