While you surf the Internet, the Internet Explorer browser keeps a cache containing the pages you already visited. This means that it saves all the contents of the pages you visited, including text and images, to a special folder on your hard-disk which is also called the Internet cache.
Because of this, when you visit a web page again, the browser is able to quickly show you the page because it already has its content in the cache, and doesn't need to get the contents from the web. This Internet cache feature helps you browse the web faster. However, someone may examine your Internet cache and see what web sites and pages you visited, what images you viewed, etc. Another problem is the fact that in time these pages that were automatically saved will take up a lot of your computer's disk space.
The Temporary Internet Files wizard allows you to examine and delete your Internet cache.
The first step of the wizard searches for temporary internet files. The second step, shown in the image above, allows you to select which temporary internet files you would like to delete. After you press the Next button again, the wizard will delete the selected pages.
All your temporary internet files are safe to delete, because when you visit a page again, and Internet Explorer does not find it in the cache, it downloads the page again from the Internet, so there will be no problem.
In order to delete your temporary internet files and other items in one go, you can also use the Quick Cleaner.
