If there is an FTP server running on the AS/400 machine, you use Windows FTP from the command prompt – or – you can browse to the AS/400 machine, which is simpler.
In Internet Explorer’s address bar, enter ftp://[and the IP address of the AS/400 machine]. You may be prompted for a user name and password. Browse where you want to place the file.
If IE doesn’t work, you can try Windows Explorer.
Otherwise, run the command, ftp (Start > Run > ftp). At the ftp> prompt, type open and the IP address (or fqdn) of the AS/400 machine. Enter your user name and password at the prompts. Hit ? to get a list of commands.
You may have to local CD to get to the source folder or you can plunk down the .CSV file in the folder from which ftp runs.
Run a get command. Remember, you are in a session on the AS/400 now so it is a get, not a put. You may need to do a binary get depending upon your configuration. At any rate, ensure you run an ls -alR to see that the file transferred with the proper size. If a get fails, you may have the file name with zero bytes contents.
Don’t forget to exit the ftp session when you are done.
