Clear Cache Feature for Internet Explorer
Microsoft has issued a small free program for cleaning out the Internet Explorer 6 temporary Internet files, cookies, and history. This can be especially useful if one of the index.dat files has gotten corrupted. Note, however, many sites that require a sign-in such as the New York Times, Amazon, Yahoo, etc. use cookies and you will have to re-enter any passwords or log-in names that are stored in cookies.
The file can be downloaded here.
