Is programming a File Monitor/Watcher Application in WF4 possible?

[FONT=Arial]Hello,[/FONT]
[FONT=Arial]I need to know if it is possible to develop an application to track file activity for a specified type in a specified folder/directory using WF4 Visual Studio 2010.[/FONT]
[FONT=Arial]Please give me helpful material/links to help me learn and implement this.[/FONT]
[FONT=Arial]A sample application to identify file events and if possible also read the file content should be helpful.[/FONT]

[FONT=Arial]I need help to realise this in VS2010 and WF4 whereas the above articles deal with implementation in earlier technologies.[/FONT]
[FONT=Arial]thanks in advance[/FONT]
