Introduction: Why Unclutter Your Laptop?
Old laptops, especially those used for experiments, quickly accumulate orphaned files. Lack of space leads to overall sluggishness and can even compromise system stability. In this article, I’ll show you how I used Claude Code to free 30GB of junk on my four‑year‑old Lenovo Legion 5 Pro.
1. Prepare the Work Environment
Before calling the model, ensure the disk is readable/writable and that administrative rights are enabled. I launched PowerShell in admin mode to avoid any permission issues.
Next, I installed WizTree, a free analyzer that reads the NTFS MFT in seconds. This step gives me an overview before any deletion.
Initial Analysis with WizTree
The scan revealed download folders, temporary installers, and video game caches—already totaling 12GB.
2. Use Claude Code to Target Junk
Claude Code is built on Claude Sonnet 5.5 and generates PowerShell code tailored to your setup. I supplied a list of critical paths and requested a full analysis.
The AI identified over 30GB of unusable space, including rarely modified system folders and hidden temporary files.
3. Comparison with Classic Tools
Programs like CCleaner or BleachBit typically clean between 1 and 5GB on a similar disk. Claude Code far exceeds these limits thanks to its intelligent approach.
Moreover, the tool doesn’t delete essential files; it proposes a verifiable list before removal.
List of Deleted File Categories
- Temporary installation folders
- .tmp files and system caches
- Residual game installers
- Obsolete Windows update logs
4. Implement the Generated PowerShell Script
The script provided by Claude Code was executed after a full disk backup. I verified each line to ensure no critical file was targeted.
The execution took about three minutes, instantly freeing 30GB of space and boosting system responsiveness.
5. Maintain Long‑Term Efficiency
To prevent future buildup, I recommend:
- Scheduling a monthly scan with Claude Code.
- Using automatic cleaning tools like CCleaner only for temporary caches.
- Regularly deleting unused download and installation folders.
Conclusion: Free Your Laptop, Boost Your Productivity
Thanks to Claude Code, I recovered 30GB of space on a four‑year‑old SSD, surpassing traditional solutions. If you’re looking for a reliable, automated method to optimize your machine, try Claude Code today.
The efficiency comes not just from cleaning but also prevention. Establish regular routines to keep your system lean.
