Find and safely clean duplicate files on Windows, macOS or Linux folders. Groups files by size then SHA-256 hash, reports wasted space, picks which copy to keep by clear rules, and moves extras to a quarantine folder instead of deleting. Use when the user says the disk is full, "ổ đầy", "file trùng", "dọn máy", "xoá file trùng", duplicate photos or videos, cleaning Downloads, freeing space, or organizing a messy folder.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Windows Duplicate Cleanup Deleting the wrong file is worse than a full disk. This skill never deletes: it reports, then moves duplicates into a quarantine folder the user can review and empty later. ## Step 1. Scope Ask which folder to scan. Refuse to scan a whole system drive (`C:\`, `/`) or system folders (`Windows`, `Program Files`, `AppData`, `/System`, `/usr`). Good targets: Downloads, Pictures, Videos, a project archive, an external drive. ## Step 2. Dry run report ```bash python scripts/find_dupes.py "D:\Photos" --min-size 100KB --report dupes.json ``` The script walks the folder, skips links and system folders, compares by size first and hashes only same-size files, then prints groups and the total reclaimable space. It changes nothing. ## Step 3. Choose what to keep Default keep rule per group, in order: 1. The copy inside the folder the user named as "master", if any. 2. The copy with the shortest path (least nested). 3. The oldest modification time. Show the user the top 10 groups by wasted space with the kept copy marked, and ask for a yes before moving anything. ## Step 4. Move to quarantine (only after a clear yes) ```bash …

How to install
mdr add ducdg88/ducpt-skills/windows-duplicate-cleanup@sha256:7a78d0dce116ca94The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
