claude-code - 💡(How to fix) Fix Allow configuring LocalCache/Cowork VM data location on Windows (MSIX install)

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.

Alternative Solutions

• OS: Windows 11
• Install method: MSIX / Microsoft Store
• LocalCache grew to 12GB in 2 days of Cowork usage
• C: drive: 117GB total, leaving only ~30GB free after Claude
• Symbolic links and junctions to D: break the app on startup
