Console.WriteLine("-------------Source Folder-------------");
foreach (string file in searchSourceFolder){
Console.WriteLine(file);
}
string destinationFolder = @"C:\Users\Koushik\Desktop\TestFolder\TestFolderMain2\";
var destinationFolderFiles = Directory.GetFiles(destinationFolder, "*.*", SearchOption.TopDirectoryOnly);
Console.WriteLine("-------------Destination Folder Before Copying-------------");

Console.WriteLine(file);
}
string[] files = Directory.GetFiles(rootPath);
foreach (string file in files){
