I'm really trying to make this filing cabinet work, but I can't find any folders of any kind that actually fit. The dimensions are very strange. The width of the filing drawer is just over 9" and the height is the exact length of a letter-sized paper. I could, in theory, store letter sized papers -- standing up -- inside the drawer, if they would actually stay up, but I can not use any type of folders since they are all bigger than the aforementioned dimensions. 

Am I missing something? Is there a way to make this work? I think I've exhausted all my internet sleuthing options and will have to return this item because I can't find a filing system that is compatible.
