1. Folder would require to be in a form of a file, compressed file (.zip for instance).
2. File compression APIs can be used to perform these tasks in JavaScript. JavaScript has no built-in approach.

Setup
Go to NuGet and install the SignalR package into a WebApplication:

Install-Package Microsoft.AspNet.SignalR

Server
Create a class that derives from PersistentConnection:

C#

using System.Threading.Tasks;
using Microsoft.AspNet.SignalR;

public class MyConnection : PersistentConnection 
{
    protected override Task OnReceived(IRequest request, string connectionId, string data) 
    {
        // Broadcast data to all clients
        return Connection.Broadcast(data);
    }
}

Setup Routing
Make a route for your connection:

Global.asax

C#

using System;
using System.Web.Routing;

public class Global : System.Web.HttpApplication 
{
    protected void Application_Start(object sender, EventArgs e) 
    {
        RouteTable.Routes.MapConnection<MyConnection>("echo", "/echo");
    }
}

If you are setting up other routes, the SignalR mapping needs to be done before the other ones.
