Hard links can share file content on the same filesystem, but they change file relationship semantics and are not equivalent to ordinary independent copies.
What to know before you begin
Hard links can share file content on the same filesystem, but they change file relationship semantics and are not equivalent to ordinary independent copies. The project offers several scanning modes and the current version may place controls differently in Krokiet versus the older GTK GUI. Follow the meaning of the option you see, not just a screenshot from a different release.
For Windows, verify that your chosen folder is accessible and that the correct graphical frontend is running. The recommended approach starts with a small test set, especially when an action could rename, move, delete or link files.
Step-by-step: Should I replace duplicate files with hard links?
- Confirm source and target files are on the same NTFS volume.
- Understand that a hard link points to the same underlying file data.
- Test with expendable copies before applying to a real library.
- Keep a separate backup outside that volume for recovery.
Important limitation
How to verify the result
Verify the intended paths open and remain consistent after edits. A scan's estimated savings or the presence of a matching group does not by itself establish which copy should be discarded.
If the procedure does not match your screen, inspect the project's own FAQ and troubleshooting notes and identify the exact release and frontend first.
FAQ
Should I replace duplicate files with hard links?
Hard links can share file content on the same filesystem, but they change file relationship semantics and are not equivalent to ordinary independent copies.
What is the biggest risk for this task?
Programs that rewrite files in place may affect all linked paths; behavior depends on the application's write method.
How do I check whether it worked?
Verify the intended paths open and remain consistent after edits.
