The past 3 weeks i have noticed lots of duplicate files taking up space in my OneDrive, not only on my Windows 10 PC but on my android phone. I've had about 1000+ random logos appear & photos duplicated about 4 times. It has slowed up my devices, and my PC is constantly uploading whenever i use it. It also makes any synced devices run slow while it is uploading and i am constantly have to stop it or pause it. I am so confused and really annoyed at this. No idea why it is happening. It's like it is corrupted or something. I've spent days deleting unwanted files and there's still loads more. I think they still are appearing. Help!
