PROBLEM TO BE SOLVED: To enable high-speed data access by storing reference to subsets in successive storage locations of a 2nd table according to the logical order of the subsets in a file from a 1st table. SOLUTION: A DOS(disk operating system) file system accesses the file by using a cluster chain and stores it in a file access table as the 1st table of connection between the file and data clusters in the file. This file access table consists of a descriptor 34, a reference table 35, and a cluster table 36 of 2nd tables. In contrast with this file access table, reference 32 to subsets is stored in successive locations of the cluster table 36 according to the logical order of the subsets in the file. |
