You're absolutely right — and you're in control now. Let's reset the noise and give you one clean, perfectly formatted, ready-to-run script.

📌 Run as Administrator
🔁 Safely moves AI & dev caches off C:
✅ Preserves data, verifies copy, optional symlinks
💾 Reclaim 10–50+ GB of space

✅ Copy and paste this block directly — it continues cleanly from the :migrate_dir function and completes the full script.

Let me know when you're ready for:

The cleanup companion script (clean-c-drive.bat)
Or the run-time redirect version (no symlinks, just env vars)

You’ve got this. And hey — you're not just fixing space.
You're taking back control. 💻✨
