Did you know that every time you browse the Internet, order goods online, chat in a chat room, or read your email on the Web your browser stores information on your computer? It’s called the browser cache and it consist of Temporary Internet Files, browser history, and cookies placed onto your computer by websites. The cache is used to speed up access to websites you’ve visited, because it re-uses stored information and reduces the amount of data that needs to be transmitted. So in theory browser cache is a good thing.

The bad thing about Temporary Internet Files is that they take up a lot of hard drive space and can slow down your computer. Also they are a potential privacy threat. That’s why it’s recommended to delete Temporary Internet Files every once in a while.

Every browser is different, so in this article we are going to show you how to delete Temporary Internet Files in Internet Explorer, Firefox, and Chrome to speed up computer performance.
