Deleting folder / directory

Hi

Thank you for a great library! It’s quite easy to work with, even though this is my first experience with C#.

So,
I am working on my first (simple) program for EV3. It is supposed to list all files and subfolders in /prjs/ and delete said files and folders when prompted.

I have managed to do every bit, except deleting the empty folders – using the DeleteFile on a folder throws an error.

Am I going about this the wrong way, or what?
