resume_download
Robo-FTP supports resuming downloads with servers that also support this feature (most do these days).
This means that if you get half-way through a large download and your internet connection drops, you can resume the download at whatever point you lost your connection instead of starting over from the beginning.
This sample demonstrates how to use the resume feature along with some other related features like looping and sending email notifications.
The script logs on and tries to download a file. If the download fails, it re-tries three times.
It uses the /resumeany option which tells Robo-FTP to resume the broken download if a partial copy of the file exists locally and the server supports resuming the download. Otherwise, it tries to download the complete file.
If it still is unable to finish downloading the file after three tries, it sends a notification email.
