Answer 1

You should use the FileSystemWatcher Class and FTP only the files that have changed. See the following VB.NET example . Specifically, you should hook into the OnChanged event .

For example:

Private Shared Sub OnChanged(source As Object, e As FileSystemEventArgs)
 ' your FTP code here
End Sub
