MOV file will not copy over to PC from iPhone?

I recorded a video today on my iPhone but for some reason whenever I copy it over it does not copy the full file over! There isn't even any pop up to say there's being a transfer. The file is 379MB. I have over 29GB space on my computer! What is going wrong and why won't it copy over the full file? I can't open the file anywhere on the computer because the full file has not been transferred.

If you mean the camera recorded video, Connect your iPhone to computer through USB cable, and then open 'My computer', click on what should say 'Apple iPhone'(possibly have a picture of a camera next to it). And then go to folder 'Internal Storage -> DCIM -> 800AAAAA'. You should find all your pictures and videos that you recorded with your iPhone. Or you may refer to this guide, it's about how to copy video from iPhone/iPod to PC, hope it helps.
