How do I add a new DOK as storage?

by JohnnyJohnny1212

I've bought today the philips 4600er 55" and I'm trying to download some apps from the market place, but it says I don't have storage and to add a USB or something, I've tried to connect a DOK and an HardDisk, but it still says I don't have storage. I know that's because I didn't made them as storage space for the smarttv, so how do I make the smart tv stoage things there?

What's a DOK? Most of those devices should be recognized, but you would need ES File Explorer to actually view them.
