What it does
- Content-based detection — duplicates are found by comparing content, not names or timestamps. A renamed copy is still a copy.
- Identical folders, not just files — folders whose contents match are reported as one result, instead of a long list of file pairs.
- Review before you remove — inspect any pair side by side, whether text, binary, or image, and decide with the evidence in front of you.
Cleanup you control
You work with Dupli and Reference folders. You mark the folder that holds the originals as the Reference. That is what makes cleanup safe.
A published safety model states exactly which actions can modify files, so you know what can change before you act.
The app also includes example cleanup workflows, such as checking incoming files against a reference library, or cleaning duplicates within one folder.
Duplicates or differences?
Use DupliWalker to find what is identical, so you can clean it up. Use DeltaWalker to see how folders and files differ.
