Go to your Control Panel...Internet Options...(under Temporary Internet Files) Click Settings....Then View Files...
The page you view next should be empty if you deleted your temporary files first... click the "UP" arrow located in the top left hand of the screen (This looks like a folder with a green arrow.) This will take you to more folders ...depending on what you have in your computer...GO TO TEMP FILES ( not temporary).... EVERYTHING in that file CAN be deleted...Your pc will go so much better without all that... all it does is record a lil of everything you have viewed. You may have pics on there that you have saved to your pc...THESE ARE OK TO DELETE...If you have it saved to your computer, you do not need to keep those that show...they are just thumbnails of what was actually seen.
