How to Use Desktop Stacks on Mac to Organize Files

Stacks is the desktop's self-cleaning mode: turn it on and every loose file folds into a tidy pile — screenshots with screenshots, PDFs with PDFs — that expands with a click and re-folds when you're done. New files sort themselves the moment they land. One toggle, and here's how to make it work for you.

Turn Stacks on

1. Right-click any empty desktop area.
2. Choose Use Stacks.

That's it — every file on the desktop collapses into piles instantly. The same command lives in Finder's View → Use Stacks menu (shortcut Ctrl + Cmd + 0) when the desktop is active, and choosing it again turns Stacks off, spreading files back out. Nothing is moved on disk in either direction; Stacks is purely how the desktop displays what's already there. It works identically on Ventura, Sonoma, and Sequoia, so the habit transfers across every Mac you touch.

Pick how files group

Right-click the desktop again and open Group Stacks By:

• Kind — the default and usually the right answer: Images, PDF Documents, Spreadsheets, Movies, each in its own pile. Your screenshot avalanche becomes one quiet stack labelled Images, no matter how fast it grows.
• Date Last Opened / Date Added / Date Modified / Date Created — piles like Today, Yesterday, Previous 7 Days. Best for people whose desktop is a rolling to-do list where age matters more than type.
• Tags — one stack per Finder tag. If you already tag by project, the desktop becomes a project shelf: everything tagged Invoices in one pile, Client A in another, untagged files in their own stack.

Working with stacks day to day

• Click a stack to expand it — its files spread onto the desktop grid. Click the stack's down-chevron (or the desktop) to fold them back.
• Scrub to peek: slide two fingers horizontally across a stack's icon without clicking and the thumbnail flips through the files inside. Spot the one you need, click, done.
• Drag onto a stack to file something by hand, or drag a file out of an expanded stack to move it elsewhere — the underlying file behaves like any desktop file.
• Open directly: scrub to a file and double-click it without ever expanding the pile.

What Stacks won't do

Two honest limits. Folders don't stack — piles are for files, so folders stay as individual icons no matter how many you keep. And Stacks is desktop-only: regular Finder windows have their own grouping feature (View → Use Groups), but the click-to-expand piles exist solely on the desktop. If your clutter lives in Downloads rather than on the desktop, Stacks can't reach it — sorting that folder is its own project.

Stacks day to day: the details that matter

Date-grouped piles are alive: at midnight, "Today" files roll into "Yesterday," then onward into "Previous 7 Days" — the desktop ages your work for you, which is exactly what a triage surface should do. Kind-grouped piles are stable by comparison, and tag-grouped piles change only when you re-tag. If a file seems to be missing, check the grouping before panicking: a .webp among your PNGs may simply be sitting in a pile you didn't think to open.

Stacks also cooperates with the desktop's other machinery. View Options (Cmd + J) applies to piles too — larger icons make scrubbing more legible, tighter grid spacing packs stacks neatly along an edge — and desktop widgets keep their own territory, so piles and widgets won't collide. Turning Stacks off is always safe: files spread back onto the grid, nothing moves on disk, and plenty of people toggle it by mood — stacked for focus during the week, spread out for the Friday clean-up when the pile finally gets dealt with.

The screenshot problem, solved properly

If your desktop is 90% screenshots, combine Stacks with a smarter capture workflow — grouped piles today, fewer strays tomorrow: organize screenshots with desktop Stacks.
