Does anyone know why? I have two files with the same extension-- .jar, I downloaded them on my desktop. somehow on the Mojave desktop, they automatically created a thing called Developer, when click on it, it has an arrow pointing downward then turns into a folder named "New Folder With Items 2", within the folder, it contains the two .jar files. Why does it do that? Is there some way I can turn this usless "feature" off? Thanks.
