Abstract
A method for downloading an attachment to a portable electronic device's attachment viewer includes: sending an initial request from the attachment viewer to a server in response to receiving an email including the attachment by the device; from the server, accessing a graph structure representing a map of the attachment previously built on the server; reconstructing the graph structure in response to the request and encapsulating the graph structure in data having an attachment viewer readable format; (i) downloading successive chunks of the data from the server to the attachment viewer responsive to successive requests; (ii) storing each of the successive chunks on the device prior to display thereof; (iii) displaying the successive chunks on the device and automatically downloading respective next chunks of the data from the server; and (iv) while chunks remain to be downloaded from the server performing (i) to (iii).
