How to sort thousands of photos into folders on a Mac

First: why not just use Apple Photos?

Because albums aren't folders. Adding a photo to an album in Photos moves nothing: the photo stays one file inside the Photos library, and an album is a list that points at it. That's fine if Photos is where your pictures live. If they're on an external drive, came off an old laptop, or need to end up as folders you can copy to someone else, albums won't get you there. The longer version is in Apple Photos or plain folders?

Decide the folders before the first photo

Sorting is fast only when every photo has an obvious home. Four to nine folders is about right: few enough to remember which is which, enough that “other” doesn't swallow everything. A set that suits most family archives:

• keep: the good ones, to sort further later if you want
• family or people
• trips
• documents: receipts, whiteboards, the photo of where you parked
• screenshots
• delete: not deleted yet, just out of the way

Make “delete” a folder instead of deleting as you go. You decide faster when a mistake costs nothing, and you can look through it once at the end.

Clear the easy piles first

Before going photo by photo, take out what a rule can find: screenshots, images forwarded through WhatsApp or Telegram, and exact duplicates. On a phone backup they are often a big share of the pile, and none of them needs a decision one at a time. How to find them: screenshots and forwards, and duplicates.

Way 1: by hand, in Finder

Free, already on your Mac, and fine for a few hundred photos.

1. Open the folder of unsorted photos, and make your folders next to it (⇧⌘N makes a new one).
2. Switch to gallery view (⌘4), so one photo fills the window and the rest run along the bottom.
3. Press space for a full-size look when you need one.
4. Drag the photo onto its folder, or ⌘-click several and drag them together. ⌘Z undoes the last move.

Where it breaks down: every photo is a drag and an aim, and the next photo doesn't come up by itself. At two or three seconds a photo, ten thousand photos is the better part of a day of dragging.

Way 2: automatically, by date

If the folders you want are years and months, you don't need to look at the photos at all. Date sorters such as PhotoSorter or FolioSort read the date each photo was taken from inside the file and move it into folders like 2019/2019-07. It's quick and it doesn't need you.

What it can't do is tell a holiday from a receipt. A folder called 2019-07 holds the beach, the boarding pass and forty screenshots, all together.

Whichever way you sort, the date that counts is the one the camera wrote inside the file. The date Finder shows often says when the file was copied or downloaded instead, which is why a restored backup can look as if it was all taken on one day.

Way 3: one photo at a time, one key per folder

This is what keyboard sorters do, and it's what cullzy is. You point it at the folder and name your piles, and a photo fills the screen. Press 3 and it moves into the third folder, and the next photo is already there. No aiming, no dragging, so the time goes on deciding.

In cullzy specifically:

• Every pile is a real folder on disk, next to the originals, and Finder can open it while you work;
• ⌘Z undoes a move, even after you've quit and come back;
• A pile can file into year and month folders inside it, so you get trips/2019/2019-07 without a separate pass by date;
• Screenshots, duplicates and forwards are found first and offered as one selection each;
• A RAW and its JPEG, or a Live Photo and its video, move together;
• Nothing is deleted. The delete pile is a folder until you decide.

It isn't the only keyboard sorter. The others, and what each is good at, are in the best apps for sorting photos into folders on a Mac.

How long will it take?

Rough numbers, with the obvious photos taking a second and the hard ones three:

Clearing screenshots, forwards and duplicates in bulk first takes a real bite out of those numbers. So does doing it in sittings: twenty minutes a night at a photo a second gets through ten thousand photos in a little over a week.

What to do with the delete folder

Look through it once, quickly, at the end. Then move it to the bin (the Trash) yourself, or keep it on an old drive if you'd rather not decide yet. Cullzy offers to send it to the bin when you finish, and asks first.
