The Wikipedia has the following information about this codepoint:
A filing cabinet (or sometimes file cabinet in American English) is an item of office furniture for storing paper documents in file folders. In the most simple context, it is an enclosure for drawers in which articles are stored. The two most common forms of filing cabinets are vertical files and lateral files. A vertical file cabinet has drawers that extend from the short side (typically 15 inches or 380 mm) of the cabinet. A lateral file cabinet has drawers that extend from the long side (various lengths) of the cabinet. These are also called side filers in Great Britain. There are also shelf files which go on shelves. In the United States, file cabinets are usually built to accommodate 8.5 × 11 paper, and in other countries, filing cabinets are often designed to hold other sizes of paper, such as A4 paper.
