<p>A file system includes a processing device that processes data for processing with at least one of a copying function to read image data of an original document and record the read image data on a sheet, a transmitting function to send and receive image data and/or character data via a communication line, and a recording function to record received image data and/or character data on a sheet, and a memory device to store the processing data processed by the processing device. The file system includes an identity determination device to determine an identity between the processing data and data stored in the memory device, and a storing management device stores the processing data into the memory device on the basis of a result of a determination made by the identity determination device. The storing management device cancels storing the processing data into the memory device when the identity determination device determines that the processing data is identical to data stored in the memory device. The identity determination device determines the identity between the processing data and the data stored in the memory device based upon information of processes with which the processing data has been processed with the processing device. The information of processes includes information of an original document associated with the processing data.</p> |
