When capturing data, all payload data is saved into the temp.pds file (PDS = Payload Data Stream). We use this for the payload data search. Each DATAx packet shown in the tree view will be written to the temp.pds stream in the order they appear. In order to know where the individual packet data starts and ends in the PDS stream, look at the temp.pdi file (PDI = Payload Data Index). Each DATA packet in the .PDS file is kept track of by a record in the .PDI stream. A PDI stream record contains the 64-bit offset within the PDS file as well as a 32-bit length field which indicates the length of the DATAx packet in the PDS stream. Note that the CRC-16 is not part of the PDS stream.
