I am creating  a method which is measures the copy time for files and folder.

 public static TimeSpan CopyFileExplorer(string filePath, string fileDestination)

    {



        string command = @"/select, " + filePath;

        System.Diagnostics.Process.Start("explorer.exe", command);

        SendKeys.Send("^(C)");

        command = @"/select, " + fileDestination;

        System.Diagnostics.Process.Start("explorer.exe",command);

        DateTime startCopy = DateTime.Now;

        SendKeys.Send("^(V)"); 



        //need to be catched when explorer finishes the copy

        DateTime endCopy = DateTime.Now;



        return endCopy - startCopy;

    }

I have tried to find when the "copy window" of explorer disappears, but I didn't be successful...
