One drive not uploading files

Try these checks in order:

1. Check whether OneDrive is actually running.
   • On Windows, a white or blue OneDrive cloud icon should appear in the notification area at the far right of the taskbar.
   • If it is not visible, select Start, type OneDrive, and open it.
2. Look for hidden or temporary files in the OneDrive folder.
   • Hidden or temporary files can make files or folders appear to stay in a syncing state.
   • In File Explorer, show hidden files and folders, then remove hidden files and folders that are not associated with files currently being edited.
   • If temporary Office files are involved, close open Office files and clear the Office document cache.
   • Warning: deleting temporary Office files can cause data loss if the files are still needed.
3. If OneDrive shows Sync pending but no file is visible:
   • In File Explorer, go to View and enable Hidden items.
   • If no hidden file appears, create a new folder, copy all files from the stuck folder into the new folder, and then delete the old sync-pending folder.
4. If TMP files are stuck:
   • Rename the file and give it a new extension, move it out of OneDrive, upload it manually to onedrive.com, or delete it.
   • Warning: do not delete TMP files unless it is certain they are no longer in use, or unsaved work may be lost.
5. If the taskbar icon is stuck on Sync pending:
   • Delete the Office Document Cache.
6. Make sure the OneDrive app is up to date.
   • Install the latest OneDrive app if needed.

If the icon keeps showing uploading at 0%, the most likely causes in the available guidance are hidden files, temporary files, Office cache issues, or OneDrive not running correctly.
