Stupid newbie question about transfer files

I install servioo pakage 0.6 in my NAS syno DS411j. Thanks, patters.
Some problems about CPU usage and otres... but mi question is simple.
I download the youtube plugin "youtube.groovy" to my win7 PC.
How in the hell transfer this file to the plugins folder?
putty does not transfer files (so I know)
Fillezilla shows mçe the "samba" folders: photo, video, audio.
Fillezilla, port 22 (SSH) don´t connect:

  Code:

Comando:   open "admin@192.168.1.160" 22
Comando:   Pass: *
Estado:   Connected to 192.168.1.160
Error:   Connection closed by server with exitcode 2
Error:   No se pudo conectar al servidor

reading forums recommend the program winscp...
At connect

  Code:

Command 'groups'
failed with return code 127 and error message
-sh: groups: not found.

At file transfer

  Code:

Cannot execute SCP to start transfer. Please make sure that SCP is installed on the server and path to it is included in PATH. You may also try SFTP instead of SCP.
Command failed with return code 127.

Help, please

can't you do it the same way as you got the serviio installation files there?

I use the patters package through Nas Package center.
The installation was noob-proof

don't you have some kind of Public (shared) folder on the NAS where you can store files? Save the plugin there, log into your NAS SSH (Putty) and move the file to the plugins folder in the serviio installation directory. If you need more details you'll have to ask patters or other users with the NAS I'm affraid

if I knew to do that with putty ... is embarrasing, but what I know to use the linux terminal shown here. nothing.
The folders exist.
/volume1/public
/volume1/@appstore/servioo/plugins

No idea how to move "youtube.groovy" from first folder to the other
