HAve just got my photos from icloud to my windows 10 laptop this past day.
HAving watched it for a bit, after clicking the button twice, thinking it wasnt doing anything due to the lack of information shown about the status of the download. I think it downloads the file only once then duplicates it to the extra duplicate folders. So no worrying about it using double the bandwidth by downloading the files twice. Let it finish then delete the duplicates. Thats what i have done anyway.
a bit confusing, some more settings would be good. Although when clicking the icloud settings button, no settings appear.
im getting out of icloud photo sharing due to the complications, (lack of settings and small amount of free storage). Im now going to use google photos cloud service, for viewing my library from all devices, instead of icloud. And ill manually offloadphotos to my pc/laptop/mac, as well, so i have a full resolution hard copy, not in the cloud, on a hard drive in my house, connected to my pc/laptop/mac.
