當系統回報您的OneDrive 1TB已經滿了，但實際的檔案只300MB，根本不到1TB，怎麼辦? 怎麼修復?
最直接的方式是重設 OneDrive（適用Windows系統）
注意：這個動作不會刪除你的雲端檔案！它只會清除本機同步快取，並重新建立同步關係。
打開「執行」（Win + R），改輸入：
C:\Program Files\Microsoft OneDrive\onedrive.exe /reset
按下「Enter」執行
→ OneDrive 圖示會10秒中後暫時消失，再過幾秒鐘後OneDrive 就會重新啟動並開始同步
→ 此時同步的資料會「重新掃描並配對」，解決錯誤使用量問題。
利用其官網的方式決解 ，以下是用CMD的方式(我用它解決的)，也有用程式介面的方式(沒用過)
