Do you have a sample workspace you could upload for reference?

Hi @dustin​ Thanks for your reply. I haven't added a sample workspace, but this one can be fast to test since it's just the Creator + filecopy writer. I've just edited my question to add the screenshots. The 2020 example creates a folder, the 2023 example doesn't! Are you experiencing the same outcome?

I haven't experienced that issue with the FileCopy writer, but I normally will use a PythonCaller or PythonCreator to accomplish that task. The code below will create a new directory (copy/paste into PythonCreator). You'll just need to update the new_dir parameter with the path you want. 

import fmeobjects
import os
 
 
class FeatureCreator(object):
    """Template Class Interface:
    When using this class, make sure its name is set as the value of the 'Class
    to Process Features' transformer parameter.
    """
    
    def __init__(self):
        """Base constructor for class members."""
        pass
        
    def input(self, feature):
        """This method is called once by FME to create FME Feature(s).
        A created Feature is emitted through the self.pyoutput() method.
        Any number of Features can be created and emitted by this method.
        
        :param fmeobjects.FMEFeature feature: Dummy FME Feature passed in by
            FME. It can be ignored.
        """
        new_dir = "E:\your_path"
        
        if not os.path.exists(new_dir):
            os.mkdir(new_dir)
        
        newFeature = fmeobjects.FMEFeature()
        self.pyoutput(newFeature)
        
    def close(self):
        """This method is called at the end of the class."""
        pass
