Hi. I'm Brian and I'll try to help.
You should be able to change your S7 to allow this. Plug it into the computer with a USB cable, then swipe down on the phone's home screen and you should see an option for "Transferring files" or "MTP". Select that and then your computer should show you a "drive" representing your phone's storage. You can then open that drive and transfer your data.
