Question: I’ve used the Export Contacts feature of the Contacts app. It said it successfully exported my contacts to the Download folder. I plugged the phone into my laptop using a USB cable and opened the Download folder using File Explorer on my laptop, but there are no exported contact files in the folder. Where did they go?
Answer: The file was actually saved, just as it said. There is a known bug with the USB file transfer protocol that may not show all newly saved files. The solution is to reboot the phone and plug it into the laptop again to force it to reload the file list. The contact file should now appear as expected.
