FileSystemWatcher multiple calls

Hello,
 I have a fileSystemWatcher in my program to monitor a given director for new files created. However there are chances that there maybe situations where two or three file are dropped at the same time. I know filesystemwatcher can handle this situation.
However I would like to know if any of you all can tell me what would happen if the filesystemwatcher is processing a set of file dropped into and while it is processing another chunk of files are dropped into it? will it process the new set of files once its done or will it not?
Thanks in advance guys!
