Is it possible to continue ftp download after reconnecting to ftp server?
If your FTP server supports RFC 3659, you'll be able to resume interrupted transfers based on the amount of data that already exists on the receiving side.
When you restart your machine, right click on the file to resume and you will be offered the choice of overwrite or resume (and a couple of others). Choose resume and off you go!
To add a schedule for file transfer, you have to create an automated transfer profile. Go to File >> New Connection Profile. On the create connection profile dialog, select the Automated Profile option. On the next page, provide the details required to connect to the FTP server.
Yes. At the protocol level, send the server "REST <seek>" before RETR to seek to a position in the file (so if you already have 1500 bytes of the file, execute "REST 1500" and it will start sending from the 1501st byte).
Here's an example:
TYPE I
200 Switching to Binary mode.
PASV
227 Entering Passive Mode (140,186,70,20,223,87)
REST 800
350 Restart position accepted (800).
RETR welcome.msg
150 Opening BINARY mode data connection for welcome.msg (954 bytes).
226 File send OK.
Yup, the specific command in the command line FTP client is "reget." The protocol command is RESTART (or REST), as documented about half way down the page in the RFC959: FTP: File Transfer Functions page.
The Windows command line client doesn't support it though, as Dave points out.
