There are two basic types of filing system access that you need to have a basic understanding of - direct and indirect access. The direct access system allows one to go directly to the files without referencing and index. All other filing systems are variations of these three methods, whether filing is done by subject, name, location, document number, data, or other combination of these. The Alphabetic filing method includes subject files, geographical files, correspondence files, organizational files and name files. Subject filing is a form of Alphabetic filing that links files by subject categories.
Numeric filing includes straight numeric, decimal and chronological filing systems.
