Duplicate Files FinderFile Review
Find duplicate files, understand the match, and choose the keeper with evidence.
Duplicate Files Finder scans a folder for exact duplicates across all file types and high-confidence visual matches across images and videos. Review reclaimable space, confidence, previews, paths, dimensions, dates, and Foldout's keeper rationale before selecting anything for Trash.

This tool is a local inspection and workflow utility for files, settings, and development tasks you control. It reviews selected local information only; Foldout does not connect to other machines, manage accounts, monitor networks, or provide a live service.
What it does
Turn duplicate cleanup into a reviewable decision instead of an automatic deletion pass.
Scan images and videos alone or include exact duplicates across every file type.
Separate byte-for-byte matches from high-confidence similar images and videos.
See reclaimable size and confidence before selecting any candidate.
Compare previews, filenames, full paths, dimensions, file sizes, and modification dates side by side.
Use an explained suggested keeper based on dimensions, size, date, and path context.
Refine video similarity when a broad first pass needs more evidence.
Export CSV or JSON findings, or move only explicit selections to Trash with Safety Center recovery.
Review before removal
See why files match before choosing a keeper.
Groups, previews, paths, sizes, and deliberate selection controls stay visible before anything moves.
02
Compare every copy side by side
Inspect real image previews, filenames, paths, dimensions, and dates together so the duplicate relationship is obvious before anything moves.
03
Apply the suggested keeper, then review the total
Select Foldout's evidence-backed recommendation for the group, then confirm the exact selected size and keeper rationale before any separate Trash action.
Why it belongs
Why Duplicate Files Finder earns a place in the toolbox.
The practical details that make this job faster, clearer, or safer than doing it by hand.
Exact and similar are different claims
Byte-identical files are grouped as exact copies, while visually similar images and videos carry a confidence level that remains visible during review.
The scan scope matches the library
Use Images and Videos for a media collection or All Files when documents, archives, project exports, and other exact copies matter too.
Comparison includes the context that chooses a keeper
Previews sit beside dimensions, file size, dates, and full locations so a smaller export is not accidentally kept over the master.
Suggestions remain explainable
Foldout states whether dimensions, size, recency, or path context drove the suggested keeper, and the user can override it.
Review can end with a report
CSV and JSON export preserve the findings when the task is an audit, while cleanup requires explicit selection and a separate Trash action.

Questions
Before you try Duplicate Files Finder
Does Foldout delete duplicates automatically?
No. Scanning is read-only and every item moved to Trash must be selected explicitly.
What is the difference between exact and similar matches?
Exact duplicates have identical content. Similar media is a high-confidence visual match and remains labeled with its confidence for review.
Can it find duplicate documents and archives?
Yes. Choose All Files to include exact duplicates beyond images and videos.
Can I save the findings without cleaning up?
Yes. Export the review as CSV or JSON.
