Prior to IE6, Internet Explorer introduced a mechanism for viewing cached files; you can access this mechanism by clicking Tools » Internet Options » General » Browsing History » Settings. In the TIF and History Settings dialog, click the View Files button. Alternatively, you can simply type shell:cache into the Internet Explorer Address Bar or the Start » Run prompt. Doing this will open a Windows Explorer window to the C:\Users\username\AppData\Local\Microsoft\Windows\Temporary Internet Files folder.
