Relocate Claude Desktop's Computer Use VM bundle

The Claude Desktop app downloads a multi-GB sandboxed VM image to power its local Computer Use / code-execution features. The app provides no in-app setting to relocate it. On a system drive that's already tight, this bundle can be the single biggest space consumer — bigger than the user's Documents folder.

This skill moves the bundle to a target drive and leaves a directory junction (Windows) or symbolic link (macOS — not yet implemented) at the original location, so Claude Desktop sees the same path it expects.

When to use this skill

• A disk scan shows C:\Users\<user>\AppData\Roaming\Claude\vm_bundles\ is a top consumer (typically 11-13 GB)
• The system drive is below 15% free and you've already cleared regenerable caches (npm, pip, Windows Update, temp)
• The user has at least 25 GB free on another local NTFS volume (need room for the move + headroom)

Do not use this skill when:

• Claude Desktop is mid-update — finish the update first; MSIX state during an update is brittle
• The VHDX is currently in use by an active Computer Use session — the move will fail (the script checks for this and aborts cleanly)
• The destination is a network drive, removable drive, or non-NTFS volume — VHDX-backed VMs need local fixed NTFS storage
