Apps
Claude
Claude Desktop stores several Electron runtime caches to speed up the app, including Chromium HTTP disk cache entries in Cache_Data, V8 code cache files in Code Cache, GPU shader and render artifacts in GPUCache, and diagnostic log files under logs. These files help the chat interface, embedded web content, and accelerated rendering start faster, but they can become stale after app or graphics driver changes; Kudu removes those temporary caches and logs without touching conversations, account sign-in, custom instructions, or settings.
Why clean Claude?
- Outdated Chromium disk cache entries can leave Claude showing old UI assets or a broken blank panel after an app update, and clearing Cache_Data forces fresh files to download
- Invalidated V8 bytecode in Code Cache after a newer Claude Desktop build can cause an unusually slow first launch, missing interface elements, or repeated renderer restarts until the cache is rebuilt
- GPUCache often becomes incompatible after a graphics driver update, leading to black windows, flickering text, or a white chat area until stale shader data is removed
- Corrupted cached responses and web resources can make attachments or embedded content fail to preview even though your network connection is working
- Large accumulated HTTP cache files can consume hundreds of megabytes over time, leaving less free space and making Claude feel sluggish when switching between conversations
- Verbose log files can grow after repeated crashes or sync errors, filling disk space while preserving messages elsewhere, so removing them trims storage without deleting chats
- If Claude repeatedly opens to a frozen spinner or partially rendered sidebar, clearing its Electron caches removes damaged local web assets that the app keeps trying to reuse
