Clean Up Linux: Find Duplicate Files with Czkawka

Duplicate files can quietly waste storage and make folders harder to manage. Czkawka is an open-source Linux utility that helps identify duplicates and other unnecessary files, while giving you control over what happens to them.

Finding duplicates

Choose which folders Czkawka should scan and which it should exclude. Hidden or system-related directories can be excluded to avoid unwanted changes. For reliable duplicate detection, hash comparison is preferable to matching only filenames or sizes because it identifies files with identical content.

Results can then be reviewed and duplicates deleted, moved, or replaced with symbolic links. Hard links are another option, but should only be used when their behavior is fully understood.

Czkawka can also find:

• Similar images, even with different resolutions, formats, or filenames

• Large files consuming significant storage

• Empty files and directories

• Similar videos, duplicate music, broken symbolic links, and incorrect file extensions
  A minimum file-size threshold can make scans faster by ignoring tiny files that offer little potential storage savings. Most importantly, review results carefully before deleting anything.
