"What is distributed file storage?
There are two broad categories of peer to peer applications:
Distributed file sharing (see P2P Filesharing ) - These are applications which allow real-time sharing of content with other user's that are also on at the same time; however, this content does not 'live' on the peer network after a certain user that is sharing this content leaves the network. It does not 'persist' over time. Examples of this kind of network are Napster and Gnutella.
Distributed file storage - These are a newer class of peer to peer applications where the peer network actually looks and feels like 'a giant hard-drive in the sky'. Files are saved into this 'space', and persist there even after the original peer that performed the insert has left the network.
