How to delete a project

I know this is a dumb question, but how do i delete a project? Before answering, consider this:

I obviously know that i can go to the project’s folder and just delete it, but i want to know if there is another way. Something inside Unity. Like, an option for delete the project using Unity itself.

As Sergio said, the only way to do this is to delete the folder which project is stored in. Why wouldn’t you do that?
