Copy files to USB or other storage - No Plex Client

So,

From time to time I have the requirement to transfer files from local storage to an external USB Drive or other attached storage, be it for archiving or whatever. The device, being a USB Stick does not have a PLEX Client installed on it so I find myself copying files manually from the local drive(s) to the Attached USB Drive.

Is it possible, or does anyone know of a plugin where I can simply choose a Episode, Season or complete series and have plex automagically copy that file to an Attached USB Drive?
