I am currently researching how to write a FTP program that will send certain text files to different FTP servers, depending on which customer owns which FTP server. Does anyone know where I can get started with this?

This program needs to:
 - run every 30 minutes and check if a file exists for a certain customer
 - if file exists, read file name and determine where to send the file
 - send the file
 - write a log entry that this certain file was sent at time/date and where it was sent

Your help is much appreciated. :)

My first step would be to search help for keywords like "upload" and FTP...
