A little-known fact about the IE History is that the information stored in the history files is not just related to Internet browsing. The history also records local and remote (via network shares) file access, giving us an excellent means for determining which files and applications were accessed on the system, day by day.
Internet Explorer:
IE6-7
%USERPROFILE%\LocalSettings\History\History.IE5
IE8-9
%USERPROFILE%\AppData\Local\Microsoft\WindowsHistory\History.IE5
IE10-11
%USERPROFILE%\AppData\Local\Microsoft\Windows\WebCache\WebCacheV*.dat
index.dat as: file:///C:/directory/filename.ext
