Finding duplicate files

dianed143@comcast.net
Are there any apps that will scan a disk for duplicate files? With all my various systems and backups, plus sometimes shooting a pic over via air drop than emailing it later, I know I have dupes I can delete to fee up some space.

I seem to remember this existed many years ago…..

Thanks
Diane

Diane,

File Buddy will do this.  https://www.skytag.com/file_buddy/  It has not been updated in a while, but it works through many versions of macOS.  There is an update planned for sometime this year.

I use the Mac app “Find Any File” exclusively. It will find all instances of the specified file name effortlessly over one or several mounted drives, as well as matches to a part of a file name. And much more. Much easier to use than the apple kludges, clean interface, available at the App Store I believe. Don’t be without it.

Gemini from MacPaw does a very good job of finding duplicates. (No URL, because I’m in an airport and can’t look stuff up easily. :-))

cheers... -Adam

Try Gemini2, from MacPaw (same folks as make CleanMyMac). https://macpaw.com/gemini 
I haven’t used it much, but it performs as advertised — it will find duplicates that are named differently, and even find similar, something I find helpful.

It's about all I use, because going after the little stuff is too much trouble and you usually have to make decisions. My drives have a fair bit of the equivalent of junk DNA, but hard drives are cheap compared to time spent.

I couldn't agree more. If I can solve a problem by throwing some money at it (Hard drives), that is a much better solution for me than wasting my time looking for little stuff. I too use GrandPerspective to find the biggies, and probably only look at that maybe once a year -or- two. Hard drives are cheap, time is priceless!

I agree! So far I’ve found a 3gb folder that was a duplicate of files in my Pictures folder. I put them in their own folder for a reason but had forgotten them. Now they are stashed on a flash drive.

In reply to this post by dianed143@comcast.net
A very old but very useful program (still working
under High Sierra) is DupScan:

http://www5.wind.ne.jp/miko/mac_soft/dup_scan/index-en.html

With this program you can specify what you want
to search for, e.g. you can search for files with
the same size, same name, same extension, etc.
but also check CRC for complete equivalence.

Re: Finding duplicate files

dianed143@comcast.net
I went with File Buddy as that was the one I remembered from way back, and I liked the format.

My low hanging fruit first netted me 200gb, mostly duplicates of movie files and I can still do some cleanup there.

My next realization was that I not only had backups of each computer on there, I had one Emergency Backup folder when a drive started to fail, along with (2) computers worth of Recovered Files when a drive *did* fail. When rummaging through those, I discovered a number of Eudora backups as it got transferred around different machines.

All that said, I went from 288gb free to 1.8TB free on a 4TB drive.

I’m going to check out DupScan as well, as I didn’t grab that the first time through.

Thanks for all the suggestions!

Diane

I would highly recommend DaisyDisk. I used to use GrandPerspective, but find DaisyDisk's interface much better for quickly locating, inspecting, and deleting large/unnecessary files. Really well designed piece of software, easily worth the price.

I‘ll throw Disk Inventory X into the mix.  

In addition to a well designed grouping of info by app, e.g., photos, music, docs, called a TreeMapView
- the output includes the Unix folders.
- a sortable list of folders/files by name and size
- all folders can be expanded to get to subfolders and files
- an option to show the free space relative to the files space
- mouse-over the TreeMapView to reveal the specific Finder file path

I've tried them all, Omni Disksweeper is the only one I like.

But for duplicates, Gemini II seems to work pretty well.
