How Embedded Chromium (Electron / CEF) Caches Bloated Sublime Merge Cache & Temporary Files
Modern web browsers and desktop apps built on Electron, Chromium Embedded Framework (CEF), or WebView2 run a full browser storage engine inside %AppData%\Sublime Merge\Cache, Code Cache, and logs. 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, Sublime Merge Cache & Temporary Files accumulates 1.5 GB – 9.5 GB of expired media blobs and stale Service Worker caches that are never evicted automatically. Clearing these cache subdirectories forces a clean storage state without deleting your saved passwords, active session cookies, bookmarks, or local databases.
