Claude Desktop Partition Caches
Claude Desktop stores Chromium partition caches under its Partitions directories for isolated web contents used by the app. These partitions accumulate HTTP disk cache entries, compiled JavaScript bytecode, GPU shader and GPUCache data, image and media cache files, and other temporary network resources so views load faster and embedded content can be reused. Kudu removes only those preview-partition cache files on Windows, while leaving sessions, IndexedDB, local storage, service-worker data, offline content, accounts, and settings intact.
Why clean Claude Desktop Partition Caches?
- Corrupted HTTP disk cache entries can make conversation panes or embedded previews load incomplete content, which shows up as blank sections, missing assets, or repeated refresh behavior
- Invalidated V8 code cache after a Claude Desktop update can leave old compiled script data behind, causing a noticeably slow first launch or sluggish panel opening until the cache is rebuilt
- Stale GPUCache and shader blobs from a previous graphics driver version can trigger rendering glitches, black panels, flicker, or choppy scrolling in hardware-accelerated views
- Oversized image and media cache files can consume hundreds of megabytes in the Partitions folders, leaving users wondering why Claude Desktop keeps growing even though chats and settings are unchanged
- Bad partition cache state can cause the same remote resources to be fetched repeatedly, which users notice as slower preview loading and extra network activity every time the same content is opened
- Outdated cached responses inside an isolated partition can keep a preview stuck on older content, so the app appears not to reflect recent changes until the cache is cleared
- Clearing only preview-partition caches removes temporary Chromium data without touching sessions, IndexedDB, local storage, or offline content, making it a safe fix for display and loading problems
