International ClassG06F 017/30Foreign Application Priority Data1993-03-22 JPAbstractA header analyzing unit extracts a header area and each table unit area in each of an old and a new executable files, and calls a difference extracting unit for each area. A segment data associating unit associates a segment data in the old executable file with a corresponding segment data in the new executable file, and calls the difference extracting unit for the associated areas. A resource associating unit associates a resource data in the old executable file with a corresponding resource data in the new executable file, and calls the difference extracting unit for the associated areas. The difference extracting unit extracts the differences in byte units between the new and the old executable files from start to end in a specified area, and saves the differences in an update file.Other References
