WebOS JS Service with External Storage

Share inI am now able to use the NodeJS or WebOS JS Service to get files from my web server.
However, one question remains that my project requires all logo files or movies files to be able to download locally to the device.
However, these files can be quite big especially movie files.
How can I store these files into the WebOS TV?
Also what I know is that LOCAL_STORAGE is also quite small. About 5 MB.
I also dont have external storage permission for simulator
Is there someone in whom I can ask to guide me on these?

Regards

Chris
