I was trying to find out what those little icons in my favorites menu in IE 5.5 were when I discovered some strange things.

I learned that they are called 'favicons' and are supposedly stored in the internet cache. So, as a test, I deleted all my internet files and rebooted. When I came back, the icons were still there.

I looked in the temporary internet files and found that all of the files were gone EXCEPT cookies and the favicon for the most recent bookmark I made.

So, where are the icon files REALLY being stored?

And why are some immune from being deleted?
