Find files fast with easy to see colors placed on file folders. Your own eyesight actually finds file folders before manual retrieval. This is the oldest method of filing and is still used extensively today.
Alphabetic letters work with colors to control the name of the file.
Colors are assigned to letters to form unique color blocks for easy site location. The first three letters of the subject name are color coded for identification. This provides a good distribution of records and backshifting is kept to a minimum. Ideal for filing systems where no other means of file identification has been established. This is a method of filing where consecutively numbered folders are placed in the file in sequential order.
