Which files am I supposed to remove?

Hey guys,

I recently decided to make my first BeamNG map. After setting up all the files succesfully, I want to edit with the BeamNG editor. But you first need to remove some files so you get an save blank map but I don't know which one to delete.

My file setup looks like this: http://prntscr.com/h9he97 (At the upper bit)
And it looks like this: http://prntscr.com/h9heip (At the bottom end)

Please, tell me which files I should delete and shouldn't.

Thanks for reading!

Oh and also, does the editor have a "undo button"?

You would have to screenshot the open folders for me to see, but you shouldn't have to delete anything to save it?

 

Thanks for the reply man but I've already fixed it. So this problem is pretty much solved and I can work on my map in peace!
