How to organise files on a Mac

Most Macs aren't messy because their owners are messy. They're messy because filing takes twenty seconds and a train of thought, every time, so it waits for later, and later never comes. The fix is a structure simple enough to keep, a few Finder settings that do some of the work, and something to handle the files that arrive every day.

1. Pick a folder structure you'll keep

Start from how you look for things, not how a filing cabinet works. Most people search by who a file is about or what it's for, so organise by that first and by date second.

• Keep it shallow. Three levels is plenty: Work / Clients / Bramblewood Joinery. Six levels deep is where files go to be forgotten.
• A handful of top-level folders. Something like Work, Home, Money, Personal and Archive covers most lives. Put them in Documents, or in the cloud drive you already use.
• One folder per client, supplier or project. Not one folder per file type. An invoice, a contract and a photo from the same job belong together.
• Archive by year. When a project ends, move its folder into Archive / 2026. It's out of the way, and still one search away.

Don't rebuild everything on day one. Make the top-level folders, then create the rest as files need them.

2. Name files so they sort themselves

A good name tells you what a file is without opening it. Put the date first, written year, month, day, so files sort in order in any Finder window:

2026-09-26 Bramblewood Joinery Invoice 2291.pdf

To rename a batch at once, select the files in Finder, Control-click and choose Rename. You can replace text, add text, or give them a format with a counter.

Skip words like “final” and “v7”. If you need versions, let the date do it.

3. How to organise your Downloads folder

Downloads is where most of the mess starts: every bank statement, invoice, installer and photo lands there with a name like statement (3).pdf. Deal with the backlog once, then deal with each new file as it arrives.

Clear the backlog

1. Open Downloads and choose View > as List, then sort by Date Added, newest first.
2. Delete installers first. Anything ending in .dmg or .pkg has done its job once the app is in Applications.
3. File anything from the last month or two into its proper folder.
4. Move everything older into a single folder called Downloads Archive. If you haven't missed it in months, you won't. It's still searchable if you do.

Stop it filling up again

• Ask where to save. In Chrome, open Settings > Downloads and turn on “Ask where to save each file before downloading”. It adds a step to every download, but nothing lands in the wrong place.
• Or in Safari: open Settings > General and set File download location to “Ask for each download”.
• Or file as they land. An app that watches Downloads can file each file into the right folder the moment it arrives. More on that below.

4. Clear the Desktop

Screenshots and quick saves pile up on the Desktop because it's always visible. Two fixes:

• Use Stacks. Control-click the Desktop and choose Use Stacks. macOS groups everything by kind, so fifty files become a few neat piles.
• Move screenshots somewhere else. Press Shift-Command-5, click Options, and choose where screenshots save. A Screenshots folder in Documents keeps them out of sight until you need them.

5. Set up Finder to help

• Show the path bar. View > Show Path Bar puts the folder a file lives in at the bottom of every window, so you always know where you are.
• Put your main folders in the sidebar. Drag a folder into the Favourites section of the sidebar and it's one click away from any window and any save dialog.
• Group by date. In a list, View > Use Groups, grouped by Date Added, sorts files into Today, Previous 7 Days and so on, which is often all you need to find something recent.
• Empty the Trash automatically. In Finder > Settings > Advanced, turn on “Remove items from the Trash after 30 days”.
• Search instead of digging. Command-Space opens Spotlight, which searches the text inside PDFs and documents, not just their names.

6. Tags and Smart Folders

Tags let one file sit in two places at once without being copied. Control-click a file and pick a colour, or choose Tags to type your own, like Tax 2026. Click the tag in Finder's sidebar to see every file with it, wherever it lives.

Smart Folders are saved searches. In Finder, choose File > New Smart Folder, set conditions like Kind is PDF and Created is within the last 30 days, and save it to the sidebar. It updates itself, and nothing moves.

Use tags for things that cut across folders, like tax time. Use folders for where a file actually lives. Trying to do everything with tags alone usually ends in a Mac full of untagged files.

7. iCloud, Google Drive and Dropbox

Pick one place as home for your working files, and use the same structure there. If your clients live in Google Drive, file their invoices into Google Drive, not a copy in Documents.

• iCloud Drive can keep your Desktop and Documents in iCloud. Turn it on in System Settings under your name, then iCloud > iCloud Drive.
• Google Drive, Dropbox, OneDrive and Box put a folder in Finder's sidebar under Locations. Anything you save there syncs like any other file.
• Optimise Mac Storage, in iCloud Drive's settings, keeps older files only in iCloud until you open them, which frees up space without deleting anything.

8. Make it automatic

The structure above only stays tidy if new files go into it. Filing by hand works until a busy week. You have three ways to take it off your plate.

Folder Actions

Built into macOS. With Automator, you can attach a Folder Action to Downloads that runs every time a file arrives. It's free, but each action is a small workflow you build and maintain, and anything smarter than sorting by name or type means writing a script.

A rules app, like Hazel

Rules apps watch a folder and act on anything that matches a rule you write: if the name contains “Bramblewood”, move it to that client's folder. They're powerful and exact, but every new client or kind of file needs a new rule. Here's how iFiley compares with Hazel.

An app that reads the file

An AI file organiser reads each file and works out where it goes, with no rules to write. iFiley does this for every download: it reads the name, the text and the names inside, weighs the folders you already have, and files it with one press of Return. It runs on your Mac and asks when it isn't sure.
