Editing Projects Within A Program

How do I copy files from one project folder to another from within a program? How do I delete another project folder (and it's files) from within a program?

It is not possible to change your project folder while in a program or to access a file outside the project folder. The only thing close to this is PROJECT which can only be run from direct mode to change the project folder. You can also use it to find the name of the project folder like so:

PROJECT OUT folderName$

This form can be used in edit mode as well.
