This is cover about investigating Internet Explorer history, cache, cookies, favorites. Lets take a look at index.dat file

Index.dat


Ubuntu, ‘Helvetica Neue’, Arial, Helvetica, Verdana, sans-serif;font-size:12px;line-height:16.1875px;text-align:justify;” />Ubuntu, ‘Helvetica Neue’, Arial, Helvetica, Verdana, sans-serif;font-size:12px;line-height:16.1875px;text-align:justify;”>Microsoft’s Internet Explorer has two primary areas of interest. One is “index.dat” database file which is used by the web browser and the browser cache. index.dat is in the format of MSIECF (Microsoft Internet Explorer Cache File Format). The index.dat file contains information of visited URLs including the accessed and modified time, the location of cache directory, HTTP headers and so on and so fourth. Almost every software uses IExplorer for displaying information and for connecting over internet. Programs like skype, Live messenger, etc uses IE. So the history of accessed urls of those applications are also stored in index.dat.

There are third party tools which actually erase the index.dat. But remember any file can be recovered in seconds and some third party tools leave traces. So the best would be to shred the index.dat file manually.
