摘要： A file managing system manages a plurality of files shared with a plurality of users. The files are linked to each other, and are controlled in accordance with link information. File control information is defined to represent a status of rights given to each of the users who is permitted to perform a processing which corresponds to one of the rights the status of which is in an on-state. The file control information is produced for each of the files. Link control information including link information representing a condition of the link between the first file and the second file is defined. The link control information further includes information which represents whether each of the users is permitted to use the link. The link control information is produced for each of the files. The access of each of said users to the files and the access of each of users to the link is controlled in accordance with the file control information and the link control information. The link control information may further include first propagation information which represents whether a processing performed on a first file is to be reflected to a second file so that a processing performed on the second file may be controlled, when the first file is processed, in accordance with the first propagation information.
