DupliWalker documentation
DupliWalker finds duplicate files and identical folders across the locations you point it at, and gives you the evidence to decide what to remove.
It is built around a single idea: deleting a file is the only step you cannot undo, so everything before it is read-only and reversible. Scanning does not change your files. Comparing does not change your files. You decide what goes, and you confirm it.
The four steps
- Scan — choose the folders to inspect, and start a search.
- Understand — read the grouped results: which copies exist, and where.
- Verify — open any two files side by side and confirm they really are the same before acting on them.
- Clean up — select the redundant copies and remove them, deliberately.
Most of the time you will spend the longest on step 3, and that is the point.
Start here
- Quick start — from opening DupliWalker to your first result.
- What is a duplicate? — why matching names prove nothing, and what DupliWalker matches on instead.
- Dupli and Reference folders — the one concept that makes cleanup safe.
- Safety model — exactly which actions can modify files.
Running DupliWalker
DupliWalker runs in your browser at app.dupliwalker.com. There is nothing to install, and the address is stable — bookmark it, or reach it from Launch DupliWalker anywhere on this site.
A desktop application is also available. The two share the same workbench and the same concepts; where their behaviour differs — chiefly in how each reaches your files — the difference is called out on the page it affects.
Inside the application, Help → DupliWalker Documentation brings you back here, and Home on the toolbar returns you to this site.
If something looks wrong
- No results, or fewer than you expected? Start with what counts as a duplicate — the usual cause is that the files differ in a way the filename hides.
- A whole folder shown as one result is intentional. See identical folders.
- Terms you have not seen before are defined in the glossary, and the FAQ answers the questions people ask first.
