This sounds like the ownership issue. Read http://support.microsoft.com/kb/308421
I've been trying to encrypt some of my documents, but there's a particular group of files that I can't encrypt, all of which are files made by Microsoft Frontpage (they are all my work in school).
I've already used Norton 360 to back up all of my documents, including this one. And I do not have Microsoft Frontpage installed into my laptop, since my last format.
How is it possible to encrypt such files? Or is it not possible to do so?
I have another question about encryption:
Will it be possible to encrypt an entire hard drive (including system files)? Is there any consequences of doing so successfully?
Would appreciate to get answers soon.
NOTE: I've already tried searching for answers to this, but to no avail. Thus I posted this topic to know more about encryption.
