Enable FXP

Hi,
I use ultra.cc to feed my NAS & local plex server.
Today, I use an FTP client to download the content from ultra.cc. Then, I upload it on my NAS. I would like to be able to use FXP so I can directly copy files from ultra.cc over to my NAS without using my system as the middleman.

My FXP client is Flash FXP.

Thanks

Greg
