The Mac OS file system can provide a lot of useful information regarding file and folder activities. The difficulty lies in determining what information you desire, and obtaining that information in a timely manner (i.e. as it happens). Once you have the raw data associated with a file system event, translating it into something useful, and then communicating that info to a user or developer is straightforward. This paper presented several ways of doing all of the above. Hopefully, you can develop new products or enhance existing products using the techniques described here.
