Onedrive Cache Clear Extra Quality -

★★★★☆ (4/5) – A crucial, under-documented tool. Use /reset , not manual deletion. Microsoft should add a “Clear cache” button in the GUI (currently absent as of 2026). Bottom line: If OneDrive is misbehaving, clearing the cache via /reset is the second thing to try (after restarting your PC). It’s safe, reversible, and fixes most sync nightmares. Just avoid doing it daily – it’s a repair tool, not routine maintenance.
