How to find duplicate files with Ricly
- Install Ricly and open it.Turn on the Finder extension when it asks (one setting), then create your free account and verify your email. In Ricly › Modules, click Enable on Find Duplicates (it’s off at first).
- In Finder, right-click a folder.Ricly looks inside every folder it contains, on your Mac or on an external drive.
- Choose Ricly › Find Duplicates…, review the groups, then move the copies to the Trash.Nothing moves until you click, and you can put anything back from the Trash.
Find duplicate files without comparing them by hand
You have done this a hundred times.
- Sort by size
- Squint at the names
- Open two files to be sure
- Drag one to the Trash
- Doubt yourself
- Put it back
- Give up
Ricly does the comparing for you. Right-click the folder, review the groups, send the copies to the Trash. It matches on content, so a renamed copy is caught and a look-alike never is.
See what else comes with itExact duplicates only: content, not names
Two files are grouped only when every byte matches. That is what makes the result safe enough to act on without opening anything.
SHA-256 on the actual bytes
Files are first grouped by size, then hashed with Apple’s own CryptoKit. A copy you renamed is still caught, and two photos that merely look alike never are. No near-matches means no false positives to second-guess.
It walks the whole tree
Right-click one folder and Ricly goes through every folder inside it. Hidden files, empty files and app bundles are skipped, and symbolic links are left alone.
Nothing is deleted, ever
Everything goes to your Trash, through the same system call Finder uses. You can put a file back from the Trash.
Different names are never auto-checked
When the copies in a group carry several distinct names, Ricly leaves them all unchecked. Those are usually templates or working versions, and the choice stays yours.
Ricly vs. Photos, the Finder, cleaner apps and the Terminal
The files are compared where they are, on your Mac. What Ricly replaces is the half hour you spend doing it by hand.

WHAT IT REPLACES
For photos, macOS has its own. Photos gathers duplicates from your library under Utilities › Duplicates, and Merge keeps one copy and moves the rest to Recently Deleted for 30 days. Ricly does the job for any folder you right-click — Downloads, a project drive, an external disk — and the groups are exact copies, byte for byte. Counted the same way as everywhere else on this site: once your account exists, and never counting the wait. What no step count shows is the doubt — by hand you are never quite sure two files are the same, and that is the part Ricly removes.
Sure, before you delete.
Every group is byte-for-byte identical, and every copy goes to the Trash rather than out of existence. You can always change your mind.
You came for one tool. 16 more come with it.
Find Duplicates is not an app you install. It is one item in a menu that also carries 16 others — same download, same account, nothing extra to set up.
13 are free, 4 are Pro. They install themselves as they ship, so the menu grows without you doing anything. Audio to MP3 will turn the bounce you just found into something you can send, and Compress Image will shrink what you decide to keep.

Finding duplicate files on a Mac: common questions
How do I find duplicate files on a Mac without installing anything?
For your photo library, open Photos and click Duplicates under Utilities in the sidebar, select the copies, then click Merge; Apple says the removed copies stay in Recently Deleted for 30 days. For files in folders, you can sort a Finder window by Size or Name and compare likely copies yourself.
Can I find duplicate files in the Terminal?
macOS includes shasum, which computes the same SHA-256 fingerprint Ricly compares: shasum -a 256 file in the Terminal. Comparing fingerprints across a whole folder tree takes a script of your own; Ricly does it from the right-click menu.
Does it work on an external drive?
Yes. Right-click a folder on an external disk or a USB stick and Ricly scans it the same way. Disk images (.dmg) are left out.
Is there a free duplicate file finder for Mac?
Ricly’s scan is free and never limited; on the free plan you can move 10 files a month to the Trash, and Pro removes that limit. For your photo library, the Duplicates view in Photos is built in.
Does it delete anything on its own?
No. Nothing moves until you press the button, and even then files go to your Trash — the same place a file goes when you drag it there. Empty the Trash yourself when you are sure.
How does it decide two files are the same?
It hashes their contents with SHA-256 after a size pre-filter. Identical hash means identical bytes. A renamed copy is caught; two similar-looking photos are not, because they are not the same file.
Does it find near-duplicates or similar photos?
No, and that is deliberate. Anything approximate produces false positives, and a false positive in a delete tool is the one mistake that is hard to take back.
Which copy does it keep?
One per group, and you choose the rule: newest, oldest, or the one in its original location (the least nested folder). When the copies carry several different names, Ricly checks nothing at all and leaves the decision to you.
Is my folder uploaded anywhere?
No. The scan and the hashing run on your Mac. Ricly checks your account and your remaining allowance, so it needs the network, but no file content leaves.
What counts against the free 10?
Files actually moved to the Trash. Scanning, reviewing and changing your mind cost nothing.
Right Click. Done.
