How do I upload video from SD Card

[JRM66]

Hi - I'm am trying to upload some video from my cameras' SD card (NOT micro SD) to my new Galaxy Note 10.1 using a Samsung SD card adapter but can't seem to find it - I think it's an AVCHD file but not sure. 'My Files' finds some folders on UsbDrive A but they don't seem to contain any video files.I can upload still photos (jpeg s) ok but not video. Please can anybody help as I'm going on vacation soon and want to be able to upload and watch my videos (and photo's) as I travel. Please explain in terminology suitable for a "Silver surfer"!
Many Thanks
John
