Many FTP servers will close a connection if the user has no action during
a specific period of time. TurboFTP effectively prevents this using the
so-called anti-idle mechanism. During the idle time TurboFTP will send dummy
random commands to the remote server, such that the server will think the
connection is still "active".
FTP servers often enforce a maximum time of no data transfer. Anti-idle
cannot help in this situation. However TurboFTP has strong auto-reconnect
capability, which will keep you connected to an FTP server at its best effort
without your manually reestablishing the connection.
