Question about USB export & advanced FTP

I have a certificate for opus 12 pro, now I want to add some extra with my certificate, I want to add USB export and advanced FTP. so I want to know about usb export and advanced FTP in detail. is there any documentation?
Q.1. Can I use the current discount coupon for 25% less price in USB export and advanced FTP?

Please send questions about sales to sales@gpsoft.com.au (or just try the discount code and see it if works for that; you can always cancel before paying).
