[Fix] Device is unreachable when you transfer files from iPad to Windows

When you’re transferring photos and videos from iPad/iPhone to Windows using File Explorer, you may get these error messages:

The device is unreachable.

Or this error message:

A device attached to the system is not functioning.

And the transferring process is aborted. To fix this problem, follow these steps:

1. Open Settings on your iPad/iPhone.
   
2. Scroll down to Photos and select Keep Originals under Transfer to Mac or PC section.
   On iPhone, the steps is similar as iPad.
   
3. Now you can transfer media files.
