Dieses Programm synchronisiert Daten zwischen mehreren Rechnern im gleichen Netzwerk und ist als Open-Source-Software kostenlos. Das Dateisynchronisierungsprogramm legt zudem Sicherheitskopien auf beliebigen Medien an und führt Kopiervorgänge in voreingestellten Zeitintervallen durch.

Dabei spielt es keine Rolle, ob die Daten auf CD/DVD, einem Netzlaufwerk, einer anderen Festplatte oder einem USB-Stick gesichert werden sollen. Per Filterfunktionen wird festgelegt, welche Dateien und Ordner FreeFileSync sichern soll. Die unterschiedlichen Kopiermodi können den eigenen Bedürfnissen angepasst werden. Einmal konfiguriert speichert man die Einstellungen in einem so genannten Profil ab.
