I have a task which needs to be notified when a image is copied to a folder. I found a example from: http://developer.apple.com/library/mac/#featuredarticles/FileSystemEvents/_index.html
It works when using command:
$ cp motorcycle.png motorcycle-copy1.png
It doesn't work when I copy a image in and paste, or I drag a new image in the folder. The fsevents_callback reacts, it menas the folder is changed. but how do I know there is a new image copied to the folder or a image changed in the folder?
