Common Lisp: creating a directory

Question

Is there a way to create a directory using common lisp. I want to first create a folder and then put my .txt .png files in that. I know that first I can create the folder externally and then using with-open-file and so on create my files inside the directory. What I want is a common lisp solution for this.
