How to clear your Windows offline files cache

If you are having problems with offline synchronization in Windows and can't seem to get it figured out, you may need to clear your offline file cache.  I've also run into problems where there is no other way to stop your offline files from synchronizing, even if you've done what you can to shut it off. I recently had this issue and found the solution at http://offlinefiles.blogspot.com/2010/09/delete-offline-files-cache-windows-xp.html. There are three different way to clear the cache, but the article in the link outlines them all in a very clear way. In my situation I had to use one of the registry hacks because I had a GPO preventing changes to offline files through the menu.
