To clean up the files you listed you should only do it in Internet Explorer. Here's how:
On the menu at the top, go to Tools and select Internet Options, then on the dialogue box that comes up the first tab is General. There is a button for "delete cookies", another for "delete files", and below them you can set the number of days to retain "history" (I use 14 days, but if you are on the internet excessively you could set it to less.)
If you are not computer savvy, don't bother with the other tabs since you could mess up your settings.
