How Embedded Chromium (Electron / CEF) Caches Bloated Notion Desktop App Cache & Asset Cache
Modern web browsers and desktop apps built on Electron, Chromium Embedded Framework (CEF), or WebView2 run a full browser storage engine inside %AppData%\Notion\Cache and %AppData%\Notion\assetCache. Every inline video preview, animated sticker, PWA offline bundle, and compiled V8 JavaScript script is written into disk-backed Cache_Data, Code Cache, Service Worker CacheStorage, and IndexedDB LevelDB tables without strict disk quotas.
Over months of daily usage, Notion Desktop App Cache & Asset Cache accumulates 1.0 GB – 5.5 GB of expired media blobs and stale Service Worker caches that are never evicted automatically.
