SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps users understand why their C drive is full, what is safe to remove, and what should be migrated instead of deleted. It reduces uncertainty by turning raw disk usage into clear, risk-aware decisions.

Core Features & Use Cases

  • Deep C-drive analysis: Scans 12 categories including system hidden files, temp caches, browser data, developer caches, large files, Docker/WSL usage, and app-specific storage.
  • Decision guidance: Produces AI-style recommendations with safety levels, reasons, alternatives, and migration suggestions instead of simple delete-or-keep output.
  • Safe execution workflow: Supports read-first analysis, cleanup guidance, rollback awareness, and staged action plans for both urgent low-space cases and routine maintenance.
  • Use Case: A developer with a nearly full C drive can ask for help, receive a prioritized cleanup plan, and learn whether Docker, npm caches, or browser data should be cleaned or moved to another drive.

Quick Start

Ask the assistant to analyze your C drive and explain which items can be safely cleaned, which should be migrated, and what actions you should take first.

FAQPage Schema
How do I safely clean up my C drive when it is almost full?

C drive cleanup requires analyzing storage pressure across 12 categories like system temp files, developer caches, and Docker usage to generate risk-aware recommendations. This ensures you safely remove junk data or migrate large files instead of blindly deleting critical system folders.

What is taking up so much space on my Windows C drive?

C drive storage pressure on Windows is typically caused by hidden system files, browser data, developer caches like npm, and Docker/WSL usage. A PowerShell-based scan categorizes these items to show exactly what is consuming your disk space and whether it is safe to remove.

How do I clear Docker and WSL storage on Windows without breaking my containers?

Clearing Docker and WSL storage safely requires scanning their disk usage and applying risk classification before deleting anything. This approach provides rollback-aware decision support and migration suggestions to prevent breaking your active containers and development environment.

Can I migrate developer caches like npm to another drive instead of deleting them?

Yes, migrating developer caches to another drive is a recommended action when your C drive is full. Instead of simple delete-or-keep output, the analysis produces migration suggestions and staged action plans to safely relocate large cache directories without losing your dependencies.

Does PowerShell disk cleanup work for routine maintenance and urgent low-space recovery?

PowerShell disk cleanup supports both routine maintenance and urgent low-space recovery scenarios. It performs read-first analysis to classify risks, generates a staged action plan, and provides rollback-aware guidance to safely free up space without causing system instability.

What are the limitations of automated Windows disk cleanup scripts?

Automated Windows disk cleanup scripts lack risk classification and rollback awareness, risking accidental deletion of necessary files. A guarded cleanup workflow provides safety levels, reasons, and alternatives for each item, overcoming the limitations of simple delete-or-keep scripts.
