Random blank videos show up in my Camera Roll after importing Photos and Videos to my PC.

I recently uploaded all of my photos and videos from my iPhone to my PC. When copying over the photos and videos, I noticed a number of files that were showing up with a "device" icon. I ignored these files and left them on my iPhone. After unplugging my iPhone and going back into the Camera Roll, there are now 45 blank video files. When I click on them and press play a blank black screen appears with no video or sound. I am not sure if these are corrupted video files or if they are random new files that were somehow created. Anyone know of a way to play these files? After realizing this, I attached my iPhone to my MacBook and the files still show up as unreadable. Below is a screenshot of what they look like on my iPhone and MacBook. Thanks for any help..
