On open desktop, right click. Properties -> appearance -> advanced Go to the "message box" and look at the color for it. I believe that is what controls the file name colors, if not tamper with a few of them. You may re set the settings by re choosing your "xp style."
That my be the cause
that is only if you are saying all of the files.. im not sure though lol sorry you prolly only meant the ones that are usually hidden..
