namespace create_folder
{
    class Program
    {
        static void Main(string[] args)
        {
            /////////////////////////////////////////////////////////
            DirectoryInfo newDir = new DirectoryInfo(@"C:/Ultimate");
            if (newDir.Exists)
                Console.WriteLine("The Folder Exist");
            else
                newDir.Create();
            /////////////////////////////////////////////////////////
            Console.Write("Drives");
            foreach (DriveInfo di in DriveInfo.GetDrives())
                Console.WriteLine("{0},({1})", di.Name, di.DriveType);
            Console.ReadKey();
        }

    }
}

so now first of all new directoryinfo(@"C:/Ultimate") in c drive a new folder will be created and the name will be ultimate you can change it and if the folder is created successfully , you will see fixed in the console if the folder already exist in then it will show the folder exist and hope you all understand the code i am not that good in c# so if anything wrong or any feedbacks comment please
