under File tab??

Hi,

My problem is to merge two files of different link layer types.

I tried merging 2 pcap files of same link type into a pcap file and
it succeeded.
But when i try to merge 2 pcapng files of same link type into a pcapng
file i got the error "*Wireshark can't save this capture in that
format.*"

Could some one please tell why the above error occurs? Also does
mergecap has support for pcapng file format ?

You need to manually specify an encapsulation type. See:
