Why am i having duplicate files added to my OneDrive?

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!

    According to your description, it's recommended to check statuses for your files in local OneDrive folder.
    Are they blue cloud icons?
    I suggest you you turn on Files On-Demand for each device where you want to use it.
    Then please go to OneDrive settings > Office tab > Under Sync conflicts section, please select "Let me to choose merge changes or keep both copies"

    Were duplicate files added with your computer name?

    • Please search "credentials," and then go to Credentials Manager.
    • Select the Windows Credentials tab.
    • Under Generic Credentials, look for any entries containing “OneDrive Cached Credentials” and remove them.
    • Restart OneDrive.

    I also suggest you reset OneDrive, this action could resets all OneDrive settings and won't let you lose any data.

    Hi, I done all the steps you said. As far as the duplicate files went it did work but I still had loads more random symbols that weren't duplicate files and I had to delete them one by one. I done it though. The reset of one drive I've been unable to do, so I've left it. How do I stop one drive affecting other devices? because it makes them run very slow when it is uploading. I can't see in the settings. I'm constantly having to pause it.

    I know this will look like a shameless plug, but I created a free mobile app for iOS and Android that finds and removes duplicate files in OneDrive (and other cloud providers). It's very fast and pretty accurate! If interested, it's called DeDuplicate - Cloud Cleaner (link). The website has all the info you need about security, how it works, etc. (pay special attention to the FAQ) I initially made this app for myself but I improved it over time thanks to users' feedback. I hope it's useful for someone else.
