Abstract

A method for updating detecting and loading CD volume indexes from a multiple-CD set to a cumulative volume table contained in a computer memory. The method employs an volume index file on each intermediate CD of the set along with a dual index file feature on the last CD of the set. The second index file on the last CD is a cumulative file of all the index files contained on all the CDs of the set. The cumulative index file on the last CD is compared to the cumulative volume table to generate a list of missing volumes which have not already been loaded into computer memory. The method permits determining whether a given CD is a single CD or a CD that is one of a multiple-CD set by detecting the presence of a second volume index file on the CD.

Claims

1. A method for detecting and loading CD volume indexes from a plurality of single-volume CD or a multiple-CD sets to a cumulative volume table maintained in a computer memory, each set including at least one intermediate CD and a last CD comprising:

a) creating a first index file on each CD of each set for the volume contained thereon;

b) creating a second index file on the last CD of each set which is cumulative of all the volumes of each set;

c) searching each CD from each set for the presence of both a first index file and a second index file;

d) comparing the CD volumes contained in each second index file detected in step c) to a listing of previously loaded CD volume names and displaying a list of missing volumes; and

e) loading the missing volumes to the cumulative volume table.
