Native files are now stored in the OS temp directory. 

Temp folder is deleted when minecraft is closed. If the Node.js process ends abruptly, the folder will not delete. As a dirty way to counter this, the directory we extract native files to is cleaned in the preloader. Maybe we'll come up with a more elegant solution in the future.
