Abstract:
1. A document processing system comprising: a controller having at least one processor, and a controller storage including random access memory and non-volatile memory; means adapted for performing at least one document processing operation under direction of the controller, which at least one document processing operation includes generation of at least one of a temporary data file and a persistent data file; receiving means adapted for receiving a secondary non-volatile memory in data communication with the controller; determining means adapted for determining a presence of an associated secondary non-volatile memory with the receiving means; means adapted for commencing at least one document processing operation after the determination of a presence of the associated secondary non-volatile memory via the determining means; means adapted for selectively directing each data file resultant from the at least one document processing operation to a one of the controller storage and the associated secondary non-volatile memory, wherein a temporary non-secure data file resultant from the at least one document processing operation is stored in the controller storage in accordance with a determination of an absence of the secondary non-volatile memory and wherein the temporary non-secure data file resultant from the at least one document processing operation is directed to the secondary non-volatile memory in accordance with a determination of a present of the secondary non-volatile memory; and means adapted for deleting the temporary non-secure data file in the secondary non-volatile memory after completion of the at least one document processing operation.
