1. In a computer storing a plurality of files in a memory device, each said file being assigned a unique identification number, a method of storing and quickly retrieving a selected file via said identification number assigned to said selected file, comprising the steps of:

  • generating a host array and storing the address of each said file in said memory device in said host array, wherein the addresses of said files are sequentially stored in said host array in the order in which the files are created;

    generating a second array contemporaneously with the generation of said host array, wherein said identification numbers for said files are sequentially stored in said second array in the order in which the files are created, and wherein said second array is sub-divided into a plurality of sub-arrays, each said sub-array including a digit from each said identification number;

    finding each said digit of said identification number assigned to said selected file in said second array; and

    calculating a pointer to the location in said host array to the address of said selected file in said memory device based upon the position of said digits of said identification number assigned to said selected file in said second array.
