Yes! Just a few days learning this thing. Factory Reset it a few times trying to get things right. Mobile setup then synced my desktop and my laptop for backup with File History, since I could not get the windows backup to complete the network backup on either of my devices. When I look at the MyCloud Home app on my phone, there are hundreds of pictures and videos that were duplicated, not from just my phone pictures, but my desktop too! Multiple copies of the same picture or video. These are NOT appearing in my desktop app, and didn’t even know they were being created. And some how, I also now have multiple duplicates like myphoto.jpg AND myphoto(1).jpg! Not sure if that occurred from multiple backups performed or if it’s being duplicated from backups on my Passport usb device. I started spend hours trying to delete them one by one. But I can almost swear that they are reduplicating themselves after I delete them! What are these files anyway, and are they really necessary? Can they be mass deleted instead of one by one with the mobile app? Are they taking up disc space on my MyCloud Home?
