What is the cache
The Temporary Internet Files (or cache) folder contains web page content that is stored on your hard disk for quick viewing. This cache permits Internet Explorer or any other browser to download only the content that has changed since you last viewed a Web page, instead of downloading all the content for a page every time it is displayed.
Sometimes however the files stored in your Temporary Internet Files folder can include small malicious applications and viruses that cause problems with your browsers. These files also affect the storage on your computer itself and can lead to low disk space.
It is therefore very important to clear the cache as often as you can.
