Just had a couple of thought on alternative was to do this, if your app
only needs to note the change when it is brought to front then you
could use this event to check.
Or you could use AppleScripts folder actions, you can use AppleScripts
to attach another AppleScript to a folder which sends an message to you
app every time something is added to the folder. You could perhaps even
do this by simple telling your app to open the added items, the you
would not have to add any special AppleScript events to your app.

Someone has released some code that does this and they basically just
do what you suggest periodically checking for any change. If you are
not to concerned with knowing immediately about any change, polling
every 5 secs or even every 5 min, then this is not much for cpu
running at 1 GHz.

Hello everyone,
I am writing a Cocoa application which detects what files are go into
a
folder, that is a hot folder. I have checked NSFileManager which
provides a
delegate method - willProcessPath: . However, it seems that
NSFileManager
doesn't have any notification center.
Then what I do is to attach a NSTimer and regularly check if there is
any new
file come into the folder. However, I am afraid that will involve a
lot of
processor resource. Would you kindly suggest another method.
