password protection for folders without encryption

Greg,
Based on your advice, I was able to manage the sparsebundle files just fine and place them in their own "images" folder on my extra internal disk drive. While I have some files that are sensitive enough that I want encryption, I also have LOTS of files that are not sensitive but I don't want other users (students) messing with them. I don't really need such strong encryption -- its just overkill. All I really want is password protection so they aren't going to go into my folders by mistake. I read somewhere that Espionage can do that for less critical files but I can't find the steps to take in the help folder or in the on-line guide. It isn't obvious from the menu options either. Please advise.
Thanks!
