Transferring Files between an iPhone and a Windows PC

Hello,

I have video files on my iPhone and want to transfer them to my computer.

The videos I want to transfer are all organized in my official Apple Files app. When I go to my computer and open iTunes, Navigate to my iPhone summary, and try to transfer files in between the iPhone and PC I cannot because I can't seem to find an option letting me transfer files directly from the Files app through iTunes onto my PC. There is an option for iMovie and a third party files app I have on my iPhone but not for the official Apple Files app. I cannot transfer them from my Files app to the third party files app. I cannot transfer them through iCloud as I have very poor internet service where I live. I want to transfer these files via usb through iTunes onto my PC. This seems like it would be incredibly easy except Apple does not want this to happen for some reason. I do not understand how I can't transfer files via a usb connection from one Computer to another.

Any advice would be helpful to transfer these files.
