I have installed iTunes on my PC.
However, when I click Photos → Sync Photos,
it says
You can choose which photos from your computer are copied to your iPhone.
It seems that it copies photos from the computer to the iPhone, but not the other way around.
Question:
How do I transfer a large video (> 2 GB) from an iPhone to a PC?
Best Answer
You can use the program iExplorer. It is free, and you can download it to view files on your iDevice. Simply plug in your phone, open iExplorer, and then on the sidebar, select Photos -> Recorded Videos.
