How to Empty the Cache on My Computer
When you surf the Internet, your browser saves copies of the pages visited into your cache folder. While the process makes browsing the Internet quicker by downloading images from your cache folder, it could also be a problem. There is the possibility that you could retrieve outdated information and your cache memory could take up too much of your hard drive, consequently slowing your computer down. You should make it a habit to clear your cache periodically. The browser you're using, which version of the browser you're using and the operating system all play a part in determining how to clear your computer cache.
