I just moved a lot of files (400GB) out of Onedrive and now The folder I moved out is bizarrely causing an PC alert error saying I have too many files in that directory (which no longer exists in onedrive. It used to have a lot of Lightroom photos in it and I never got an alert like this Now that the folder is not even there I want you guys to clear this error. Why the error is there in the first place is crazy - we use Onedrive to store files like photos and we should be able to store as much as we want so long as we are not going over our quota. So two concerns: I have zero files in a nonexistent folder that is giving me an error about too many files in it, And you guys shouldn't keep me from storing things like my photo directories by saying there are too many files If I'm not going over my quota.

    Hello AJedynak,

    Sorry about the hassle. Since the folder is already outside OneDrive, this looks like OneDrive holding on to stale sync info rather than a real problem with your files.

    On your second point, the 300,000 figure is a recommended sync limit for performance, not a storage cap and not tied to your quota. Going over it can make sync slower, but it shouldn't get your account flagged. Microsoft also started rolling out syncing of up to 1,000,000 items in April 2026 for eligible devices.

    Here's what I'd try, in this order:

    • Open OneDrive on the web, go to the Recycle bin, and empty it.
    • Reset OneDrive: press Windows key + R, run %localappdata%\Microsoft\OneDrive\onedrive.exe /reset, then reopen OneDrive from Start. Microsoft says this doesn't delete your files, but it will do a full resync.
    • If the alert is still there, unlink and relink: OneDrive Settings > Account > Unlink this PC, then sign in again and choose Use this folder when prompted.

    Before relinking, I'd make sure your Lightroom photos are safely backed up in their new location.

    A stale OneDrive sync state can keep showing a folder-related alert even after the folder was moved out of OneDrive. The supported steps in this situation are:

    1. Verify the folder is no longer inside the local OneDrive folder in File Explorer.
      • If the folder is outside the OneDrive folder structure, it is no longer part of OneDrive sync.
    2. Pause and resume OneDrive sync.
      • Select the white or blue OneDrive cloud icon in the notification area.
      • Select More > Pause syncing... and choose 2, 8, or 24 hours.
      • Select More again > Resume syncing.
      • This can help clear stuck processing states.
    3. Check the total file count in OneDrive on the PC.
      • Open File Explorer.
      • Right-click the OneDrive folder and select Properties.
      • If Contains is more than 300,000 files, reduce the number of files in OneDrive. Removing shortcut folders or stopping sync for SharePoint libraries can also help.
    4. If the alert is tied to a folder that was deselected from sync and now says it already exists, use one of the supported workarounds:
      • Delete it from the PC. This is safe if the content is still available in OneDrive online.
      • Or move the folder outside the PC’s OneDrive folder to remove it from OneDrive and keep it only on the PC.
    5. If duplicate or stale sync metadata is involved, clear the local OneDrive pre-sign-in settings file:
      • Press Windows key + R.
      • Enter %localappdata%\Microsoft\OneDrive\settings and select OK.
      • Delete PreSignInSettingsConfig.json.
      • Then restart OneDrive.
      • If that does not resolve it, uninstall and reinstall OneDrive.

    About the file-count concern: OneDrive guidance states that if there are more than 300,000 files, sync can take a long time and reducing the number of files is recommended. That is separate from storage quota.
