How can I use bluetooth to transfer files between my iPhone 6 and my Windows 10 laptop?

I had the (possibly mistaken) belief that one of the functions of Bluetooth was to easily transfer files between two nearby devices. I could certainly do this with my Android phone and my Linux laptop.

I now have an iPhone and a Windows laptop for work and I can't seem to transfer files between the two. Is one or other of the operating systems crippled in some way, or am I doing something wrong? The devices are paired* but sending files does not succeed.

* well they used to be. Windows still thinks they are, but iOS is now saying my laptop "is not supported" (something changed in recent update to iOS 11???)

iOS 11.x does not support sending files using the Bluetooth OBEX protocol. So unfortunately you can't transfer files using this method.

You may be able to transfer files over Wi-Fi with apps like FileExplorer.
