If you press Enter without entering a file path, the script will set the ""root_directory_path" to an empty string. Here's the specific part of the code that handles this:

Since "root_directory_path" would be an empty string, when the script tries to create subdirectories, it would use the current directory as the base directory. Essentially, it would create the subdirectories directly in the directory where the script is running.

To handle this more gracefully, a check can be added to ensure that the user has entered a valid path.  The script now passes the user's input to Python's built-in "os.path.isdir" function to check whether the entered path is a valid directory. If it's a valid path, the function will return "True".

The os.path.isdir function is a part of the Python "os" module. It uses the operating system's file system to check whether a given path exists and whether it is a directory. Here's a bit more detail on how it works:

When you provide a path as an argument to the os.path.isdir function, the function checks if that path exists in the file system of the computer where the script is running. The function then verifies whether the provided path is indeed a directory (as opposed to a file or some other type of path).
