Czkawka: Hard Drive Nearly Full? Find Piles of Duplicate Files in a Flash

Solves in one sentence: Got tons of duplicate images, documents, and music eating up space on your computer? Czkawka is written in Rust and scans several times faster than similar tools.

Running out of disk space inexplicably? The culprit is likely a mountain of duplicate files quietly taking over your hard drive — the same photo saved in multiple folders, installer files overlapping with backups, duplicate tracks in your music folder…

Finding these duplicates manually is impossible. Czkawka makes it incredibly fast.

What Is Czkawka?

Czkawka (Polish for “hiccup”) is a duplicate file finder and disk cleanup tool written in Rust. It can find duplicate files, similar images, empty folders, large files, and more.

The problem it solves: Quickly find duplicate and junk files on your hard drive to free up disk space.

Key Features

• Duplicate files: Find identical files by name or file hash
• Similar images: Use perceptual hashing to find visually similar images at different sizes
• Large files: List files above a specified size
• Empty folders: Scan and delete empty directories
• Temporary files: Find cleanable temporary files
• Zero-byte files: Find empty files

User Experience

• Blazing-fast scanning speed (thanks to Rust), 3-5x faster than similar tools
• Both GUI and command-line versions available
• Clean interface with good Chinese language support
• Supports Linux, Windows, and Mac

Download

• GitHub Releases: https://github.com/qarmin/czkawka/releases
  • Windows users download files containing _windows.exe

Tip: The GUI version is recommended. If you only need basic features, the portable version will suffice.
