edtFTPj/PRO is a Java library which
allows developers to add rich file
transfer capabilities to their
applications with minimal effort. It
supports standard and secure FTP
operations, firewall protocols, and
recursive operations on directories
(including mget and mput).

edtFTPj/PRO implements FTPS (explicit and
implicit modes), and SFTP. Built on the
solid foundation of the stable and mature
edtFTPj code-base, edtFTPj/PRO benefits
from the robustness that years of
open-source development and thousands of
installations brings.
Unlike edtFTPj, edtFTPj/PRO is a
commercial product. It uses the edtFTPj
API, so it is straightforward to upgrade
an existing edtFTPj application to secure
transfers. The recursive capabilities can
be used directly on edtFTPj classes.
