Most often file sharing is the common and basic requirement when users work on a particular domain or area of interest. Users can use software that connects in to a peer-to-peer network to access shared files on the computers of other users (i.e. peers) connected to the network. Files of interest can then be downloaded directly from other users on the network. So this concept is similar to a distributed file system where files are distributed across the network but the users have an illusion of a centralized file system and also avoids its high complexity and cost of implementation. Emphasis is more on location and access transparency.
