I have a file on NTFS that holds accumulated information that will take forever to recreate. I marked it as 'archive' and 'system', so that it would not be obvious to notice or mishandle, but what I really want is to put some kind of lock on it, so that deleting it would only be possible when providing a password or fulfilling some other condition.
Is there a tool that can help me? perhaps some hidden Windows feature?
thanks, Yuval =8-)
