Certain app won't move to SD card? Also how to move pics and vids to SD card?

[AC Question]

I have a Samsung Galaxy Nook with a 16 GB SD card. I've used 2GB so far. I found this one app about dinosaurs and I installed it. It says its able to move to SD cards, but when I checked it, it wasnt moving. I kept clicking 'Move to SD card' but it never went on. Am I doing something wrong? Also, how do I add videos and pictures to my SD card?

Welcome to Android Central! Some apps just don't let you move to SD, and others only let you move a very small portion. It's possible that this app can't be moved, but someone forgot to code it properly to make sure the option didn't show up.

To add videos and photos to your SD card, use either a file manager app to move them there, or connect the device to your computer via USB and move the files using Windows Explorer. You could also unmount the card (in Settings>Storage​), remove it, and insert it into the computer, and move files directly to the card.
