Microsoft Internet Explorer keeps a "cache" on your hard drive. A "cache" a collection of files saved automatically to help make web browsing faster. However, the cache can become corrupted or damaged which can slow down your web experience or make web sites appear to be unavailable. To remedy the problem, you can tell Internet Explorer to delete the files in your cache and start over. Deleteing cache files does not in any way affect your computer in a negative manner. In fact, most Internet Explorer problems can be resolved by clearing your cache.
