摘要：
A file management apparatus includes a file storage portion and a manipulation portion. The file storage portion stores a plurality of files therein. Each file includes one or more data structures. Each data structure includes one or more elements. The file storage portion further identifies each file with a file identifier and identifies each data structure within the file with an internal identifier and with the number of data structures contained in the file. The position of each data element and the number of data elements within a data structure are also identified. The manipulation portion manipulates the structure of the data stored in the file storage portion by employing the file identifier, the data structure identifier, and element position.
