Hi,
There are different ways to save a selection of the 90MB file.
1: Mark 2 packets and save the selection
Let say, the number of packets in the 90MB file is 90.000.
Right-click on the 1th and 20.000th packet (Packet Summery Line) and choose
Mark Packet (toggle).
File -> Save As -> Packet Range -> select First to last marked -> save
Unmark those packets and mark the 20.001th en 40.000th packet etc.etc.
2: Use a display filter and save de selected packets.
3: Editcap
C:\Program Files\Wireshark\editcap
http://www.wireshark.org/docs/man-pages/editcap.html
C:\Program Files\Wireshark>editcap -c <20000> <90MB.pcap> <SplitFile.pcap>
With the option -c you can define the maximum number of packets per file.
The result will be 5 output files, numbered from 00000 to 00004:
SplitFile.pcap-00000 20.000 packets
SplitFile.pcap-00001 20.000 packets
SplitFile.pcap-00002 20.000 packets
SplitFile.pcap-00003 20.000 packets
SplitFile.pcap-00004 10.000 packets
