Our customer has emailed us 2 PCAP files, both of type pcapng.
I was able to export the first one via File/Export Specified Packets and K12 text file shows up in the dialog under the Save as type: option menu.
When I tried it on the second one, only 7 filetypes showed up in the option menu: Wireshar/...-pcapng Wireshark/tcpdump/...-pcap Modified tcpdump -pcap Nokia tcpdump -pcap RedHat 6.1 tcpdump-pcap SuSE 6.3 tcpdump-pcap Wireshark/tcpdump...-nanosecond pcap
