Abstract

A computer having a file management system is presented. The file management system includes a plurality of application programs, a plurality of data files, a plurality of class data structures and a plurality of object data structures. Each class data structure includes a reference to an application program within the plurality of application programs. Each object data structure includes a reference to a class data structure from the plurality of class data structure and a reference to at least one data file from the plurality of data files. The use of object data structures adds a layer between a user of the computer and data files. This allows for the computer to refer to an object data structure and associated access files using a tag which is inaccessible to the user. The user refers to an object based on the physical location of the object on the screen. The user may also give the object data structure a name, which is wholly unconnected to the value of the tag. This allows a user to, for instance, give two objects in the same directory, the same name. Additonally, the file management system includes a plurality of link data structures, each link data structure including a reference to a first object data structure in the plurality of object data structures which serves a parent object of the link, and including a reference to a second object data structure in the plurality of object data structures which serves as a child object of the link. Child objects and parent objects are not necessarily the same for each link data structure.
