Accessing 360 File share

I still use my 360 as I haven’t actually bought an Xbox 1, I’ve took many screenshots from various firefights and games and am not sure how I would be able to transfer these screenshots to my pc. Is there a way to do this? A trick or something. Cause as of now I have no idea how to do that. Could I use a USB to transfer the image files xbox and bring it to my pc that way?
