Get folder path from Explorer window

Question

I have a pointer to an opened Explorer Window and i want to know its full path.

For Example:

int hWnd = FindWindow(null, \"Directory\");

Answer 1

If you run spy++ and target Expolrer window you will see that Title or Caption of that window usually reflects the current directory opened by user

So what you need is that using window handle you need to get its caption. I would suggest following links that will guide you

How to get the name of an External window in C# Application?

Answer 2

Here's a way to obtain that information:

    IntPtr MyHwnd = FindWindow(null, "Directory");
    var t = Type.GetTypeFromProgID("Shell.Application");
    dynamic o = Activator.CreateInstance(t);
    try
    {
        var ws = o.Windows();
        for (int i = 0; i < ws.Count; i++)
        {
            var ie = ws.Item(i);
            if (ie == null || ie.hwnd != (long)MyHwnd) continue;
            var path = System.IO.Path.GetFileName((string)ie.FullName);
            if (path.ToLower() == "explorer.exe")
            {
                var explorepath = ie.document.focuseditem.path;
            }
        }
    }
    finally
    {
        Marshal.FinalReleaseComObject(o);
    }

EDIT: I changed ie.locationname, which was not returning the full path, to ie.document.focuseditem. path, which seems to be working so far.
