Fails with long network paths on Windows

[jessielw]

I was testing this library out and it fails to write (just hangs) with very long Windows path names. Example path name that was failing.

\\JLW-UNRAID\dl_share\downloads_nvme_temp\random_folder\downloads\Hostage.2005.Remastered.BluRay.1080p.DTS-HD.MA.5.1.AVC.HYBRID.REMUX-FraMeSToR\Hostage.2005.Remastered.BluRay.1080p.DTS-HD.MA.5.1.AVC.HYBRID.REMUX-FraMeSToRä_temp\Hostage.2005.BluRay.720p.DD.2.0.x264-group_images\img_comparison\%da_source__%d.png

Edit if I create a small function to convert this to a UNC path it works fine.

def convert_to_extended_path(path: str) -> str:
    """
    Convert a standard or UNC path to an extended-length path
    with the \\?\ prefix for Windows if needed.

    Parameters:
    - path (str): The original file path.

    Returns:
    - str: The extended-length file path if needed, or the original path.
    """
    # Ensure we're manipulating a string
    path = str(path)
    
    # Normalize slashes to backslashes
    path = path.replace('/', '\\')    

    # Check if the path is already an extended path
    if path.startswith("\\\\?\\"):
        return path

    # Check if the path length exceeds 260 characters
    if len(path) > 260 or any(ord(char) > 127 for char in path):
        # Check if the path is a UNC path (starts with \\)
        if path.startswith("\\\\"):
            extended_path = "\\\\?\\UNC" + path[1:]
        else:
            extended_path = "\\\\?\\" + path
        return extended_path

    return path

Is this intended?
