In order to efficiently reproduce the captured data, Wireshark also implements its own packet reassembling technique. 41 Instant Wireshark Starter Wireshark collects the different chunks of packets of the fragmented data and then reassembles it to reflect the complete file through the packet bytes panel. For example, an HTTP GET request (HTML page) can be broken into smaller data packets. Once the transmission is complete, Wireshark reassembles the different packets and creates a single reassembled HTML page.
You can prepend the selected file to the currently open one, append it, or merge the files chronologically based on their timestamps.
