File cabinet is more of a stylish type. The material is NOT heavy at all. I was able to lift on my own with out hesitation (female 5" 3' 130lbs.) It does come with keys and a lock to keep private but i am not sure how reliable it would be. It is not one of those heavy duty metal kind of cabinets. If you are looking for an extremely confidential file cabinet i would opt out of this one. If it is for your everyday docs then i would definitely recommend.
