File Cabinets have various types of filing. The filing type is dependent upon the types or sizes or the documents to be filed. The two main filing types are vertical filing and lateral filing. Vertical filing is where files are stored in the drawer from front to back. Vertical file cabinets tend to be deeper than lateral file cabinets. Lateral filing is where files are stored from left to right. Lateral file cabinets tend to be wider than vertical cabinets and about as deep as a file folder is wide. Roll filing is where large documents, such as blueprints, are rolled and stored standing up or in slots. Flat filing is where documents are simply laid flat in the drawer.
