Well, there must be a reason why you can't open this or any other file. What is the real reason? Does this file exist there, or is there only a so-called thumbnail image of this file? What does Properties show? In the meantime, have you copied this file or done something else with it? Or maybe you have done a new installation of Windows and kept the files on their location. Have the permissions of the file(s) not changed? There must be some reason.
