Preflight Checklist
Problem Statement
On Windows, Claude Desktop installed via MSIX/Microsoft Store stores all Cowork VM data
in C:\Users<user>\AppData\Local\Packages\Claude_pzs8sxrjxfjjc\LocalCache
This folder grows to 10-12GB with normal Cowork usage (creating apps, running tasks)
and cannot be moved to another drive. Attempts to use symbolic links or junctions
break the app entirely.
Users with small C: drives (117GB with Windows + other apps) run out of space quickly.
The "Move" button in Windows Settings only moves the executable, not LocalCache.
Users with limited C: drives run out of space quickly with no official workaround.
Proposed Solution
Add a setting in Claude Desktop to configure the data/cache directory location,
similar to how other Electron apps (VS Code, etc.) allow custom data paths.
Alternatively, document an official supported method to move LocalCache to another drive.
