From CT3

The applet periodically uploads any file resident in the router to an external file server.

Usage guidelines

The applet requires no additional configuration, but you have to edit the parameters in the source code. The responses to various command propts (action 2.0 through 4.0) assume that the file prompt level is set to alert. If you have configured file prompt quiet, there is no prompting after the copy command.
