Abstract
The present invention efficiently displays in a tree structure form a file operation history. A file storage identifier, an operation identifier, and a count are stored as additional meta-information in an alternate data stream with respect to each file stored in a client terminal file system. The operation identifier manages a number of operations (operation generations). The count manages copy frequencies. This meta-information is also sent to a management apparatus, and used for displaying the file operation history in a tree structure form.
