A Microsoft file hosting and synchronization service.
The two blue circular arrows mean OneDrive is still processing changes. Since it is stuck at 90 files / 7.9 GB remaining and showing 0%, the most likely causes supported here are:
- OneDrive is processing a large amount of data
If many files are being synced, OneDrive can stay on processing for a while. - A large file is blocking sync
Very large files such as ZIP archives, long videos, or Outlook PST/OST files can cause OneDrive to stay on Processing changes. Move large Outlook data files out of OneDrive, or stop syncing folders that contain very large files. - A file is open or locked
Close any file that is currently open, then wait and check whether OneDrive resumes syncing. - Unknown or hidden files are blocking sync
Select the OneDrive cloud icon in the taskbar to view files that are open, syncing, or recently synced. - Storage may actually be full
If OneDrive storage is full, OneDrive cannot upload, edit, or sync new files. Existing files remain read-only. In OneDrive on the web, open Manage your OneDrive storage or Storage used to check what is taking space, empty the Recycle Bin, and confirm the account is under quota.
For a personal Microsoft 365 account, OneDrive can report full because:
- the storage quota was exceeded,
- a shared folder pushed the account over storage,
- the subscription expired or renewal failed,
- a storage promotion expired.
Recommended order:
- Click the OneDrive cloud icon in the taskbar and check whether it names a specific sync problem.
- Close any open Office, PDF, or other files stored in OneDrive.
- Check OneDrive storage online and empty the Recycle Bin if needed.
- Look for very large files, especially ZIP, video, PST, or OST files, and move them out of OneDrive if present.
- If it still stays on Processing changes, use Unlink and re-link OneDrive to reset sync.
If the account is over quota, OneDrive will not sync new files until storage is reduced or more storage is added.
