I'm embarrassed to admit it, but I don't know how to load pictures onto my own computer other than to save for a file for processing! Pitiful, isn't it! If you go to Lowe's Home Improvement: Appliances, Tools, Hardware, Paint, Flooring
and search for "united plastic milk crates", that is the item. On their website they show the large and small sizes. I purchased the medium. Its' dimensions are 16x16x12 (measuring from outside edges). There is a little lip/notch that you can't see in the picture, but that's what holds the hanging folders as that "lip" is down a little from the outside edge of the crate. Good luck in your search!
