How to create a directory in plunker?

Question

How do you create a directory in a plunker ? or if there is a directory how do you create a new file/move in that directory ?

Do you need to use an external tool for this ?

Ex : I have edited this existing angular2 plunker, I have created myFile.ts file, I would like to move it in the app folder.

Double click on the filename. Then you can rename it from myFile to app/myFile.
