Unfortunately it doesn't guarantee no overflows completely, although
passing the processing off to a queue certainly helps. In my
application I still have to have watch for overflows even though the
files to be processed are loaded into a queue, and then subsequently
processed on another thread,
The FileSystemWatcher buffer is overflowing. You can handle this event
by adding something like this to your code that sets of the
FileSystemWatcher:
// ProcessOverflow is a method setup to handle FSW buffer overflows.
fsw.Error += new ErrorEventHandler(ProcessOverflow);
