Help, how to copy video files to WD Passport?

I have been transferring VHS tapes to my computer, but it is running out of hard drive space. How do I copy these files to a WD Passport. I do not want to backup my computer, I only want to move the videos so I can get them off my computer. Can I move them like I would if I was transferring them to a USB drive?

Exactly the same procedure as any other external hard drive (USB or otherwise.)
