By the way guys, if you are using FTP-3DS, you can just use windows explorer and type this into the navigation/location bar:
ftp://192.168.x.x:5000
Replace the x's with the correct values displayed on your FTP-3DS of course. This will basically use windows explorer to view your 3DS files. No need to install any software. Also, I haven't tested this with FTBrony but in theory, it should work.
