How do I remove temporary Internet files from the hard disk of my computer to free up space or to ensure I have the latest version of a page?

"Temporary internet files are web pages and information elements such as graphics which are stored on your hard disk as you view them. This speeds up the display of pages you frequently visit because your browser can open them using the information stored temporarily on your hard disk, instead of downloading the information from the Web. In Internet Explorer, select Internet Options (the last option) from your drop down Tools menu on the main menu bar. A floating window appears and in the default window you will see a Temporary Internet Files heading (the second option), and under this heading you will see a button marked Delete Files. Click on this button and all the temporary files will be deleted from the Temporary Internet Files folder."
