Well I found this on the internet (Stuckoverflow): Here's Best and Fastest Way To List All Directories and Subdirectories by Skipping System.UnauthorizedAccessException A simple recursive method with action to retrieve at realtime, preparing a list and returning to parent takes a lot of time, this call back function helps a lot to retrieve at realtime instead of preparing and returning back

using System.IO;

private static void ListDirectories(string Path, Action<string> Listen){
    try
    {
        foreach(string Node in Directory.GetDirectories(Path)){
            Listen(Node);
            ListDirectories(Node, Listen);
        }
    } catch {}
}

using System.IO;

private static void ListDirectories(string Path, Action<string> Listen){
    try
    {
        foreach(string Node in Directory.GetDirectories(Path)){
            Listen(Node);
            ListDirectories(Node, Listen);
        }
    } catch {}
}

Usase

static void Main(string[] args)
{
    ListDirectories(@"C:\", (dir) =>
    {
        Console.WriteLine(dir);
    });
}

static void Main(string[] args)
{
    ListDirectories(@"C:\", (dir) =>
    {
        Console.WriteLine(dir);
    });
}
