As you explore the Web, your browser saves copies of pages, usually including graphics, on your hard drive. This is called a 'cache' and the idea is that if you want the same page again it will look in the cache for it instead of downloading the whole thing again. What most users don't know is that the cache isn't cleared until it is full, which means that after you have finished surfing the web, most of your visited pages are still stored on disk. Neither Explorer or Navigator provide much to help you check out the cache, but cache Explorer lets you make use of this saved material. It isn't quite as easy as using the web but you can search for files that contain keywords and look at pages by clicking on them. Well worth a try.
