For those who are unaware of this hidden gem. Remote File Access is activated in BB LINK, and on your device - Settings/BlackBerry Link switch on and tick Download Files Over Mobile Network.
What it does is allow you to connect up to 10 PC's that have Link installed and associated with your BID. From there you can access files on your PC, stream video and music, albeit one track at a time. View and edit documents, and share all files via email, BBM, NFC, or download the file to your device.
Im so surprised Blackberry have not made a big issue of this feature
