You're on the right track to use Java. Try this bit of code (be sure 

    public void anything(String s, Atom[] args) {

The string s represents the path of the folder you want to make.

You're on the right track to use Java.  Try this bit of code (be sure 
to import java.io.File):

	public void anything(String s, Atom[] args) {
		f = new File(s);
		f.mkdir();
	}

Hi Dan! - I want to do the same thing - cross platform folder creation. However I am a complete Java novice - I get compile errors when i try to compile the following:

public class CreateFolder extends MaxObject

    private static final String[] INLET_ASSIST = new String[]{

    private static final String[] OUTLET_ASSIST = new String[]{

        declareInlets(new int[]{DataTypes.ALL});

        declareOutlets(new int[]{DataTypes.ALL});

        setInletAssist(INLET_ASSIST);

        setOutletAssist(OUTLET_ASSIST);

public void anything(String s, Atom[] args) {

/Applications/MaxMSP 4.6/Cycling '74/java/classes/CreateFolder.java[ 26 ] cannot find symbol

/Applications/MaxMSP 4.6/Cycling '74/java/classes/CreateFolder.java[ 27 ] cannot find symbol

compilation of /Applications/MaxMSP 4.6/Cycling '74/java/classes/CreateFolder.java failed.

Sure. In Java, you have to delcare the type of your variable.

You need to tell Java what type of variable "f" is in the first place 

- take a look back at my original code - you'll see this line towards 

Alternatively, you can do what f.e. suggested, all in one line, 

modifying your current f = new File(s) line:

You need to tell Java what type of variable "f" is in the first place 
- take a look back at my original code - you'll see this line towards 
the top, which is what you need to add:
