• file_not_found: The requested file doesn't exist (download)
• parent_not_found: The parent directory doesn't exist (upload)
• permission_denied: Access denied for the operation
• is_directory: Attempted to download a directory as a file
• invalid_path: Path syntax is malformed or contains invalid characters
