Monitorer un transfert de fichiers

Voici mon programme pour transferer un fichier de mon directory à un ftp server. j'aimerais que les fichiers de mon directory qui sont actualisés soient automatiquement transférés vers le Ftp. En bref je veux monitorer le transfert des fichiers de mon repertoire au ftp.
