Re: Folder Password ?
The most sure-fire way is either to host the files elsewhere and protect them or just to zip / rar them up with a strong password.
All sorts of other ways do exist, but they're rarely more than hiding the folder, or stopping you viewing its contents through windows explorer. Setting it as hidden for example might work to ward off very casual users, but I'd never advise using it for information I never wanted anyone else to see!
