Abstract
A method of managing storage of a file in a network environment includes storing, in a central repository, tracking information of copies of the file on storage server systems in the network environment. The tracking information in the central repository is used to identify plural copies of the file. Information pertaining to the plural copies of the file is communicated to a client system. One or more requests responsive to the information pertaining to the plural copies of the file are received from the client system to delete one or more of the copies of the file.
