Temporary Internet Files are, in fact, the cache of the Internet Explorer. This means that when you load a web page with Internet Explorer, it is saved on your computer so that if you later decide to open the same page again, it will open a lot faster. Temporary Internet Files improve speed of web browsing and also make possible so called offline browsing, which gives you the ability to open the web pages from cache even when you are not connected to the Internet.

Despite all these positive things about Temporary Internet Files, they have one big drawback: they compromise your privacy. Everyone with access to your computer can look into your Temporary Internet Files folder and see the sites that you have visited in the past. You can manually delete the contents of Temporary Internet Files folder but this will not erase all traces of the pages because a special file called Index.dat is placed in this folder and it will still preserve the names and even the dates of your first visits to many pages.

You can use Easy SystemCleaner to clean all traces from the Temporary Internet Folder.
