How do you transfer video files and photo files from camera to laptop

[AC Question]

My laptop doesn't recognize my camera as a drive when I plug it into a USB port. How can I transfer video files and photo files from my camera to my laptop?
Thanks. My phone is a Nexux 6P and my laptop is running Windows 8.1

try a different cable and make sure the phone is unlocked when you connect it to your laptop
