Uploading files to Arduino Yun

Hi

Im following this video here:

and I want to upload files to the yun-sd card but according to the video whatever files/folders he places into his sketch directory along with his sketch.ino file get uploaded to the sd card, but in my case it doesnt happen. I hit upload and the sketch goes into the yun but no folder or files get put onto the sd card because im checking via ssh on the card.

Help please…
