Do you want to move items from your computer to this card, and then have the contents available on your Note? Or do you want to move things from the Note to the SD card?
For moving from PC to card (something you'll probably do during an initial load up of photos, music, etc.) I would pop the card into your computer card reader and use your computer to drag the contents to the card, then pop the card into the slot in your Note. If you have many different types of files, I would organize them into folders (video, music, pictures, etc.)
To move files that are already on the Note onto the SD card, you can use a file browser such as My Files (ships with Note) or one from the Play Store (many on this forum like ES File Explorer, free) and do a cut/paste operation.
You might also check out AirDroid to move files wirelessly between PC and your Note (also free in the Play store).
To make your external card the default for video, one method is to launch the camera app and switch into video mode. In the lower left corner of the screen, tap the cog (settings). Scroll down to "Storage" and tap to choose either Device or Memory card
I have Just bought a 64gb micro sd card and I see no way to simply transfer files on to it so how do I please anyone ?
Also how do I make the card default for recording video etc ?
