Capturing "Delete World" event

[pjlasl]

I have created a single player mod that builds a cfg file for the world being played. I would like to be able to have those cfg files be deleted when the player deletes the world.

 

What is the event that I can capture to accomplish this?

 

Thanks!

I guess I don't understand you response. (I am new to this minecraft mod world  ).

 

How would this Class help me?

I am storing coordinates that allow players to teleport to. If this is doable in this class, could I get an example of how to do it?

Thanks for the quick replies! I will look into this. If I have anymore questions I will ask.
