I used to be able to do this with my Galaxy S5, though that was always on Windows 8, I'm on 10 now.
When I connect to my computer to find my backup folder it is just a blank white icon that is 0kb, but if I look at it with ES File Explorer I can see everything fine. I see no way to upload a folder through onedrive or drive and ES File Explorer won't let me share over 100 files. I have over 600 files in the backup and I don't want to have to manually select all of them.
What is going on? How can I back up my back up to my PC? All other files and such are easily accessible through the computer
EDIT: Fixed, if anyone else is having this problem, create a folder from your computer, then move the TB folder into that folder that was created on the computer, and then it should be able to be copied from phone to computer
