摘要

An entry property 2 contained in an entry property identifies normal or system. The normal represents an entry of entity data. The system represents an entry which describes a definition of flags. The flags represent attribute information of a file. The flags are defined by an apparatus or a user. An entry property 3 identifies valid or invalid of the entry. An entry property 4 represents whether or not a file registered to the entry references another file. A referred counter represents the number of files referred from another file. When a designated file is referenced from another file, a referring file list represents a file which references the designated file. With these information, a reference relation of files can be described. <IMAGE>
