To create an spt file, first open WPE PRO. Then you’ll probably need to log a packet which you want to add to the send list (unless you want to write the packet manually).
Select “Send” tab and right click the packet you want to add.
Click “Add to Send List”.
The packet will appear on the list. Double click it.
A window has opened, where you can modify the packet.
You can also change size of the packet if you need.
Name your packet and click Ok button.
The name will appear on the Send List. You can add how many packets you like.
When your list is finished, click the floppy disk icon to save it as an spt file.
Name your file and click save button.
You’ve created your spt file. You can use it now with WPE PRO.
