title: Checking for new files in a folder
body: <p>I need to monitor a folder to see when new files are created and then have the file processed and then archived.</p>
  
  <p>Its the actual detecting of new files i'm struggling with...I understand that I need to be looking at the FileSystemWatcher thing, but was wondering if anyone knows of any examples of its usage in this way to get me started?</p>
  
  <p>Say my folder is "C:\Temp\", I need to know as soon as any file with a ".dat" extension appear.</p>
  
  <p>Sorry for the vague question, I just havent been able to find what I'm looking for with various google searches.</p>
  
  <p>Thanks in advance</p>
