To view an internet site your browser needs to download an exact copy of that internet page including all the pictures, advertisements etc. These downloaded internet pages are located in a folder called Temporary Internet Files (also called internet cache).
Resizing your Cache
By default Internet Explorer allocates 10% of your drive. This was fine years ago but today with the size of these new drives, 10% is just too large and increases the chances for corruption.
Click the Settings button, adjust the TIF size to 50 mb, click OK....
I have mine set at 61MB (DEFAULT)
In a nutshell, yer temp files are a rememberance of pages you've visited that are stored so that the next time you visit them they load quiker..If your using dial up, yer better off making your cache a tad bit bigger verses broadband
