A filing cabinet is a big metal box with shallow drawers inside that can hold papers. Think of it like a big toolbox where you keep all your important papers, just like your mommy and daddy keep their important papers in their big box. You put your papers in different folders and you label them, just like when you place your toys in different boxes according to what they are. When you want to find a paper, you just look for the folder it's in and pull it out. It's like when you want to find your favorite toy car, you just look for the box where you keep it!
