video – Importing pictures from phone (using usb) to pc desktop

When I connect my I phone to a pc desktop using a usb cord I get a notification that pops up on my screen asking if the computer can access all photos and videos when connected to the computer.if I push allow this bring up another screen asking if I want to import photos and videos onto photos or drive or if I want to open device to view files on file explorer or on media player, in other words the screen allows you to pick from 4 different options of ways to import photos from I phone to that computer. Simply because I connect my I phone to the computer and give it access to photos and videos does not mean all my photos and videos import automatically correct?
