        Args:
            path: Path to directory.
            glob: A glob pattern or list of glob patterns to use to find files.
                Defaults to "**/[!.]*" (all files except hidden).
            exclude: A pattern or list of patterns to exclude from results.
                Use glob syntax.
            silent_errors: Whether to silently ignore errors. Defaults to False.
            load_hidden: Whether to load hidden files. Defaults to False.
            loader_cls: Loader class to use for loading files.
              Defaults to UnstructuredFileLoader.
            loader_kwargs: Keyword arguments to pass to loader_cls. Defaults to None.
            recursive: Whether to recursively search for files. Defaults to False.
            show_progress: Whether to show a progress bar. Defaults to False.
            use_multithreading: Whether to use multithreading. Defaults to False.
            max_concurrency: The maximum number of threads to use. Defaults to 4.
            sample_size: The maximum number of files you would like to load from the
                directory.
            randomize_sample: Shuffle the files to get a random sample.
            sample_seed: set the seed of the random shuffle for reproducibility.

        Examples:

            .. code-block:: python
                from langchain_community.document_loaders import DirectoryLoader
