If you have decided to change the amount of space that is allocated to the Temporary Internet Files folder, be aware that you may experience a decrease in performance if the value is set too high or too low. For example, if the amount of hard drive space available for the folder is set too high, the Temporary Internet Files folder may take up a large portion of your hard drive with outdated information. (Remember that many Web sites are updated regularly). On the other hand, configuring a value that is too low can increase the amount of time it takes for IE to display Web pages.
When the size of the Temporary Internet Files folder reaches the maximum amount of available hard drive space, IE automatically removes older files to make room as needed. So when you are configuring the amount of hard drive space the folder can use, keep in mind that if you set the folder size too high, you may be retaining outdated Web site information. Conversely setting the maximum size too low slows the system because a low value doesn’t let you store as many Web sites in the Temporary Internet files folder and Web sites stored in the Temporary Internet Files folder load significantly faster.
To adjust the Temporary Internet Files folder settings, open the Tools menu in IE and click Internet Options. From the General tab click the Settings button. In the Settings dialog box, move the slider bar to set the amount of hard drive space you want the Temporary Internet Files folder to use. Click OK to apply your changes.
