Cannot upgrade my MK3S to 3.14 firmware

So I am trying to upgrade my firmware to 3.14.  I downloaded the latest .bbf file and copied it to a blank fat32 USB drive on the root level.  I put the flash drive into the printer and then rebooted the printer.  Nada.  Nothing.  Does not see the file at all and will not upgrade.  It is currently running 3.13.2.  I tried connecting to the printer via USB cable to my Windows PC and then open up the latest Prusa Slicer app and went to the upgrade command on the menu.  That wants a hex file.  If I show all files and then select the .bbf file it starts but then quickly pukes and quits as the file is not a hex file.

The printer works but I get update requests every time I load a new .gcode file.

Mmmm, I think that is a MK4 feature! No? Connect with a USB cable to the printer, then use Prusa Slicer. Then select Configuration, and Update Firmware.
