Method and system for managing data in a communication network

A method and a system for managing one or more files in a communication network are provided. The system includes a server, a first client, and a second client. When the first client places a file in a virtual data drive of the first client, data segments and metadata associated with the file are uploaded at the server. The server generates a first representation of the file. The server then sends the first representation of the file to the first and second clients. The second client stores the first representation of the file in its local storage. The second client can then send a request to the server to access the file based on the first representation of the file. The requested file is sent to the second client by the server. The sent file is not cached by the second client, if the file is a secured file.
