using System.IO;
private void Form1_Load(object sender, EventArgs e)
{
FileSystemWatcher fsw = new FileSystemWatcher(@"E:\", "*.txt");
fsw.EnableRaisingEvents = true;
fsw.NotifyFilter = NotifyFilters.LastWrite | NotifyFilters.Attributes;
fsw.Changed += new FileSystemEventHandler(fsw_Changed);
}
public void fsw_Changed(Object Sender, FileSystemEventArgs e)
{
if (e.Name == "Test.txt")
{
MessageBox.Show("File Changed !!");
}

either via a control called FileSystemWatcher
like this

or via a timer that will check on the file on every period of time and update the application on that.
