I remember years ago, using MS Word 97 in either Windows 98 or XP, I managed to create a password lock for a file that I use to this day - even now using MS Word 2007. I don't remember exactly how I did it. I can't seem to be able to do that at all now.
Seen a few ways to hide a file/folder using a convoluted script and pay through the nose to get specialized software.
There must be an easy way to do this.
