Transferring files from USB drive to ATV

I’ve read in the forum how to transfer files from the ATV to and external drive, i wish to do the opposite.

I need to transfer tons of GBs from my external HD to the ATV via direct usb connection, via WI-FI the wait is sooooo loooong, it takes forever!

I may have missed that tutorial in the forum, can it be done? Help please… thx
