Mobile apps often accumulate "Offline Files" and image thumbnails that can consume significant phone storage.

To understand the necessity of clearing the cache, one must first appreciate the function of the cache itself. In the architecture of OneDrive, the cache acts as a bridge between the local solid-state drive and the remote Azure servers. When a user accesses a file, OneDrive often retains a version of it locally to ensure that subsequent opens are instantaneous, rather than subject to the latency of an internet download. Furthermore, the OneDrive client maintains a local database—a specific set of hidden files—that tracks the library IDs, file versions, and sync status. Ideally, this system operates in the background, a silent partner in the user’s workflow. The user sees a green checkmark and assumes the digital and physical worlds are in perfect alignment.

★★★★☆ (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).
