I know about the "folder options" one so please don't tell me about that one. There are secret directories in Windows XP whose contents I want to delete.
Thanks D G for the tip.
No by secret I mean secret and yes I know a lot about the system files. I know which ones are windows files and which aren't.

I take it you are making a reference to the Registry which is where you will find the Internet browsing history, your user data, your search engine history of every, search that you ever made, passwords, profile history of you and all other users and the automatic file access stamp which is used every time you carry out a search. The good news is that all of these and more can be disabled or removed from the Registry and by doing so will increase your privacy, performance and security.
