Find What Is Taking Up Space on Your Windows PC With AI

The problem

Your PC says storage is getting full, but you may have no idea whether photos, videos, downloads, old installers, project files, temporary files or application data are using the space. Randomly deleting large files is risky. Instead, let AI inspect the storage and show you where the space is going first. The goal is simple: FIND FIRST. DELETE NOTHING.

What you need

• A Windows PC
• Codex
• The folder or location you want Codex to inspect, such as C:\Users\YourName\Downloads or C:\Users\YourName\Documents. If you deliberately want a wider inspection, you can use C:\.

Safety first

THIS IS AN INSPECTION-ONLY TASK. Codex must not delete files, move files, rename files, uninstall programs, clear caches, modify Windows settings, edit the registry or modify system files. A large file is not automatically safe to delete: some large folders belong to Windows or installed applications. The purpose of this tutorial is only to find where the storage is going. BIG DOES NOT MEAN SAFE TO DELETE. A large video may be important, a large application folder may be required, a Windows folder may be essential, and an old installer may be removable. This tutorial helps you find things; it does not automatically decide what should be deleted.

Steps

1. Choose where Codex should look. Start with a personal folder such as Downloads, Documents or Desktop before scanning the entire Windows drive. A smaller folder produces a faster, easier-to-understand report.
2. Give Codex access to the relevant folder or location through the normal Codex workflow. You do not need to use PowerShell or any command-line tools yourself.
3. Paste the supplied inspection prompt. Replace [FOLDER OR DRIVE PATH] with the location you want inspected.
4. Read the report. Look first at the biggest folders, biggest individual files and possible cleanup candidates. For example, it might show LARGEST FOLDERS: Downloads — 18.4 GB, Videos — 11.2 GB, Documents — 6.8 GB; LARGEST FILES: Downloads\old-video.mp4 — 4.6 GB, Downloads\setup-old-version.exe — 2.1 GB, Videos\holiday.mov — 1.8 GB; POSSIBLE CLEANUP CANDIDATES: setup-old-version.exe — 2.1 GB, appears to be an installer, NEEDS HUMAN REVIEW before deleting. Do not immediately tell Codex to delete everything on that list. This tutorial intentionally stops before cleanup. If you later want to remove files, make that a separate controlled task where each candidate is reviewed first.

What success looks like

Before: Windows says your drive is almost full and you do not know why. After: you have a ranked report showing where most storage is being used, for example: 1. Downloads — 18.4 GB; 2. Videos — 11.2 GB; 3. Documents — 6.8 GB. It can also identify a largest individual file, such as old-video.mp4 — 4.6 GB. Important: nothing on the PC has been changed.

If it goes wrong

If Codex produces too much information, send this follow-up: The report is too large. Do not make any changes. Please simplify it. Show me only: 1. the 10 largest folders; 2. the 10 largest files; 3. their sizes; 4. their locations; 5. whether each appears to be personal data, an application/system item, or something you cannot confidently identify. Do not delete or modify anything. If Codex cannot inspect the full drive because of permissions, start with a personal folder such as Downloads, Desktop or Documents instead.
