Change backup location for Apple Devices on Windows
Is there a way to change backup location for Apple Devices on Windows? The default location on my c: drive is full.
Nope. There is no way to change the backup folder location within the Devices App.
You can however leverage the SymLink ability of Windows to redirect the existing backup folder to another location and even another hard drive all together. That makes anything added to the original folder from that pint forward, be forwarded to the new location automatically so no space is used up in the original location.

The instructions in the link above reference iTunes, but it will work exactly the same for the Devices App.
