Here’s a good tutorial it’s confusing because it uses the destination of the world file to YOUR OWN local worlds file unlike many many other dedicated servers which have thier own directory for the world file so you just need to change the name in the BAT file to your world name

Thank you so much. I will follow these instructions as best as I can.
