Windsurf IDE
Built on Electron and VS Code components, Windsurf IDE stores Chromium HTTP disk cache entries in Cache_Data, V8 compiled script data in CachedData, extension download and extracted package caches in CachedExtensions, and rotating renderer and extension-host logs under logs. These files speed up startup, webview rendering, marketplace and extension loading, and update checks, but they can become stale after IDE, extension, or Electron updates; Kudu removes only those disposable caches and logs, not your projects, settings, accounts, or installed extensions.
Why clean Windsurf IDE?
- Invalidated V8 bytecode in CachedData after a Windsurf or Electron update can make the first few launches unusually slow while windows and command palettes rebuild their script cache
- Corrupted Chromium HTTP cache entries in Cache_Data can leave sign-in pages, settings webviews, or extension marketplace panels blank even though the rest of the IDE still opens
- Old CachedExtensions package data can keep an extension from unpacking or updating cleanly, which shows up as extensions stuck on installing, reloading, or failing to activate
- Renderer and extension-host logs can grow across repeated crashes or verbose diagnostics, wasting disk space and making the profile folder unexpectedly large
- Stale web assets in the disk cache can cause mismatched UI resources after an update, leading to missing icons, broken styling, or panels that render incorrectly until the cache is rebuilt
- Repeated cache churn leaves many small files under Windsurf's profile directories, which can noticeably slow antivirus scans, backups, and profile sync on startup
- CachedData is stored as many compiled-code blobs; when they no longer match current scripts, you may see sluggish command search, delayed sidebar rendering, and a one-time CPU spike as Windsurf recompiles them
