😂 You have a love-hate relationship with iPhone. You can actually use Microsoft edge for the file transfers. That's what I use to send and receive stuff from my iPhone to my system and vice-versa. Although, you'll have to use data for the sending and receiving processes and I'm not sure you can send heavy files like movies.
Or better still, you can send stuff to yourself (your number) on WhatsApp, then login to your WhatsApp through your system and then download the file, that works too but not for heavy files.
I even use the email or iCloud method actually.
But just imagine, all that stress.
