Remarks

FTPFileSystemWatcher listens to FTPConnection events and (optionally) polls the FTP server every [!:RefreshPeriodSecs] to detect changes.

Three events are provided for notification of changes on the remote file:

Event	Triggered when FTPFileSystemWatcher detects that..
Created	...a file has been created on the server.
Changed	...a file has been created on or uploaded to the server.
Deleted	...a file has been deleted on the server.
