Hmm, finding threads trickier than I thought. Here are two that may be of interest. Ortherwise start one yourself in the software forum?
No direct url for download on this thread so will need to use the 2 below http://cws.internet.com/ftp.html http://www.thefreesite.com/Free_Software/FTP_freeware/ If you want to talk to a programer themselves and bounce questions of him perhaps.
