Which of the following is not a method of filing

Filing methods describe how records are organised and accessed on a storage medium. The recognised methods taught at this level are:

• Sequential filing, where records are stored and read one after another in a fixed order, usually by key field.
• Serial filing, where records are stored in the order they arrive, with no particular sorting.
• Random (direct) filing, where records are stored and retrieved directly using an address calculated from the key, without reading through other records first.

Geographical is not one of these established filing methods; it describes a way of grouping information by location, not a technique for storing and retrieving records on a computer system.

Exam takeaway: when a question lists filing or file-organisation methods, expect sequential, serial, random (direct), and sometimes indexed-sequential; any term describing a real-world classification such as location, alphabet, or subject is a distractor, not a filing method.
