I don't see any reason for this to not work other than invoking Start method e.g.

Create instance

private readonly FileOperations _fileOperations = 
    new FileOperations("C:\\OED", "C:\\uisides", "*.txt");

Fire it up

private void StartButton_Click(object sender, EventArgs e)
{
 _fileOperations.Start();
}

Hello there.
First of all, "C:\\Users\\family\\Documents\\Monitor" will register as "C:\Users\family\Documents\Monitor", but @"C:\\Users\\family\\Documents\\Monitor" will register as "C:\\Users\\family\\Documents\\Monitor".
With that out of the way, I still do not know what you are asking. Are you getting any errors? Does something not work? You can use the Directory class to do everything you want.

With regards,
Alvin.
