You often don't need to pair to send files. I just did it on Android sending to Win 11.

Receiver steps:

1. Double-click bluetooth taskbar icon

2. "Send or receive files via Bluetooth

3. Receive files then wait for sender & transfer

4. Choose location to put the files

Sender steps:

1. Choose file

2. Press Share

3. Choose Bluetooth

4. Choose target device

Four steps on both sides. Slow for a few MB photo though.
