using System;
using System.IO;

class Program
{
    static void Main()
    {
        string folderPath = "C:\\path\\to\\folder";
        string fileExtension = ".txt";

        string[] filePaths = Directory.GetFiles(folderPath, "*" + fileExtension);

        foreach (string filePath in filePaths)
        {
            string fileName = Path.GetFileName(filePath);
            string parentFolderName = Path.GetDirectoryName(filePath);

            Console.WriteLine("File Name: " + fileName);
            Console.WriteLine("Parent Folder Name: " + parentFolderName);
        }
    }
