Thanks for the wonderful program!
I have to automatically upload some weather data onto a webserver. Due to some quirks of our firewall (which I couldn't overcome ) Windows's built-in FTP client couldn't upload anything. Similarly failed many other FTP clients, like WinSCP. FileZilla worked, but astonishingly it doesn't support scripting.
CoreFTP saved the day - it supports scripting and works wonderfully in our strange environment! Thank you!
