Quick Answer
Auslogics Duplicate File Finder is a free, Windows-only tool that finds duplicate files by name, size, date, or content. It is a solid pick for a quick cleanup if you match by content and scan only your own folders. If you need Mac or Linux, or want exact SHA-256 matches with a record of what was removed, use an alternative. To test a few files right now, check up to 10 files free online.
What Auslogics Duplicate File Finder Does
Auslogics makes Windows maintenance utilities, and Duplicate File Finder is its free tool for one job: finding copies of the same file and helping you delete the extras. It is available from the Auslogics website and the Microsoft Store.
What you get:
- Flexible matching. You choose whether files count as duplicates by name, size, modified date, or content.
- File-type filters. You can narrow a search to images, music, videos, documents, or other files.
- Removable drives. USB flash drives and memory cards can be scanned as well as internal drives.
- A safety net. Deleted files can go to the Recycle Bin, and Auslogics includes a Rescue Center for restoring removed files.
For a home PC with a cluttered Downloads folder, that covers most of what people need, and the price is hard to argue with.
How to Use Auslogics Duplicate File Finder Safely
- Back up first. Copy the folders you plan to clean to another drive.
- Pick folders, not drives. Select your own data, such as Documents, Pictures, Music, or an external backup drive. Leave
C:\WindowsandC:\Program Filesout. - Turn on content matching. Two different files can share a name and size. Content matching compares what is inside.
- Review every group. Keep the copy in the folder you actually use and select the rest.
- Delete to the Recycle Bin, not permanently, so you can undo a mistake.
- Check your files and apps still open before you empty the Recycle Bin or delete the backup.
Limits and Reasons to Look for an Alternative
The biggest risk with any duplicate finder is what you point it at. Windows and installed programs keep identical copies of DLLs, icons, and config files in several folders on purpose. A whole-drive scan lists them as duplicates, and deleting them can stop apps from launching. That is a usage problem rather than an Auslogics bug, but it is the most common way a cleanup goes wrong.
Other reasons people move on:
- Windows only. There is no Mac or Linux version, so mixed households and teams need a second tool.
- No exportable record. For client archives, migrations, or shared drives you may need a report of what was kept and what was removed.
- Recurring cleanups. If duplicates keep coming back after every sync or import, you may want to compare folders or watch them for changes, not just delete copies once.
Auslogics Duplicate File Finder Alternatives Compared
| Tool | Platforms | Matching | Cost |
|---|---|---|---|
| Auslogics Duplicate File Finder | Windows | Name, size, date, content | Free |
| dupeGuru | Windows, Mac, Linux | Content, filename, picture mode | Free, open source |
| PowerShell Get-FileHash | Windows (built in) | Exact (SHA-256) | Free |
| FolderManifest | Windows, Mac, Linux | Exact (SHA-256) only | 7-day free trial, $59 lifetime or $7/month |
dupeGuru: free and cross-platform
dupeGuru is free and open source on Windows, Mac, and Linux. It matches by content or filename, and its picture mode looks for similar images, which neither Auslogics nor FolderManifest does. The interface is plain, but if you left Auslogics because you moved to a Mac, it is the closest free replacement.
FolderManifest: exact matches with a plan you approve
FolderManifest hashes each file with SHA-256 and groups only files whose content is identical, so renamed copies are caught and two different files are never grouped. You choose the folders, review the plan, approve what is removed, and keep a report of what changed. The same app compares folders, watches them for changes, and verifies backups and migrations, so it helps with the cause of duplicates as well as the cleanup. It runs locally on Windows 10/11, macOS (Apple Silicon and Intel), and Linux.
What FolderManifest does not do
It does not find visually similar photos or near-duplicate audio, and it is not free like Auslogics. If a one-off cleanup on a single Windows PC is all you need, the free tool may be enough.

Free Option With Nothing to Install: PowerShell
Windows can list exact duplicates on its own. This prints every group of files under a folder that share the same SHA-256 hash:
Get-ChildItem -Path "C:\Users\You\Pictures" -Recurse -File |
Get-FileHash -Algorithm SHA256 |
Group-Object -Property Hash |
Where-Object { $_.Count -gt 1 } |
ForEach-Object { $_.Group | Select-Object Path, Hash }It only reports and never deletes, so it is a safe first look. Our guide to finding duplicate files on Windows walks through it step by step.
Frequently Asked Questions
Is Auslogics Duplicate File Finder free?
Yes. Auslogics Duplicate File Finder is a free Windows utility. You can download it from the Auslogics website or the Microsoft Store and use it to search for and delete duplicate files without paying.
Is Auslogics Duplicate File Finder safe?
The program itself is a long-running tool from an established Windows utility vendor. The risk is in how you use it: scanning a whole system drive groups program and Windows files that apps need. Scan only your own data folders, match by content, and review every group before deleting.
Does Auslogics Duplicate File Finder compare file contents?
It can. You choose whether files are matched by name, size, date, and content. Matching by name or size alone can group different files, so turn on content matching whenever you plan to delete what it finds.
Does Auslogics Duplicate File Finder work on Mac?
No. It is a Windows-only program. On a Mac, dupeGuru (free) or FolderManifest (exact SHA-256 matching, Apple Silicon and Intel) are options.
What is the best alternative to Auslogics Duplicate File Finder?
For a free cross-platform tool, dupeGuru runs on Windows, Mac, and Linux. For a free option with nothing to install, PowerShell Get-FileHash finds exact duplicates by SHA-256. For exact matching with a reviewable plan and a record of what was removed, FolderManifest runs on Windows, Mac, and Linux with a 7-day free trial and no card.
Does FolderManifest find similar photos?
No. FolderManifest only groups files whose bytes are identical. Resized, edited, or re-saved photos count as different files. If near-duplicate photos are the problem, use a similarity tool such as dupeGuru picture mode.
