Saving and Loading Packets

Network Monitor allows you to save the prepared packet to a file (in the binary form). You may later load this packet from a file. This feature also allows you to treat any binary file as contents of a packet.

In addition to binary export, you may copy the decoded value or the entire line to the Clipboard by bringing up the context menu and selecting either the Copy Value or Copy Line commands.
