# See where your Mac's disk space really went

> See what's filling your Mac with an interactive, hardlink-aware storage treemap. Drill into the biggest folders, then clean with every file shown first.

Freshist's Analyze tool draws your storage as an interactive treemap, so the biggest folders are the biggest boxes. Hardlinked files are counted once, and you can drill into any folder.

**TL;DR:** Analyze is Freshist's disk space analyzer for Mac: an interactive treemap where each folder's area matches its size, with hardlinks counted once so totals aren't inflated. Drill into the largest folders to find what's using the space, then deal with it under the same rules as the rest of the app: you see it first, and removals go to the Trash.

## What it does

### Analyze — See where your disk really went.

An interactive treemap of your storage, hardlink-aware so nothing is double-counted. Spot the forgotten 40 GB folder in seconds, then act on it — safely.

- Interactive storage treemap
- Hardlink-aware size accounting
- Drill into the biggest offenders

## How it keeps you safe

- **Show before you remove:** Every file is listed with its exact size before anything happens. No blind “one-click clean”.
- **Trash, not delete:** Everything goes to the Trash so you can undo. Permanent deletion is separate and explicitly confirmed.
- **Refuse when unsure:** Risky or ambiguous items are never pre-selected. They're flagged “review” for you to decide.
- **Zero telemetry:** No analytics, no accounts, no tracking network calls. It's a design constraint, not a promise.

## Why the Storage settings only get you halfway

macOS has a storage overview under **System Settings › General › Storage**. It splits your disk into categories such as Applications, Documents and System Data and suggests a few cleanups. It's a good place to start, but it doesn't tell you *which* folders are large. If System Data shows a big number, you can't click through to see what's inside it. Our guide to [System Data on a Mac](/blog/what-is-system-data-on-mac/) explains what usually ends up there.

A disk space analyzer answers the next question: where, exactly, is the space?

## How a treemap shows your disk

Analyze draws your storage as a treemap. Every folder is a rectangle, and its area matches its size. Folders sit inside their parent folders, so the layout follows your disk's structure.

This works better than a sorted list for one reason: you see the whole disk at once. A large folder buried four levels deep is as easy to spot as one at the top level, so you don't need to know where to look. Click into the largest block to see what's inside, and keep going until you reach the files themselves.

## Why hardlink-aware matters

A hardlink is a second name for the same data on disk. Package managers, build tools and some backup systems use hardlinks to avoid storing the same file twice. An analyzer that adds up the size of every path counts that data once per link, and the total can come out larger than your disk.

Analyze is hardlink-aware: each piece of data is counted once. The numbers in the treemap add up to what's really on your disk, so the folder that looks biggest really is the biggest.

## What usually turns up

Every Mac is different, but a few things come up again and again when people first look at a treemap:

- Installers, archives and videos that have sat in Downloads for months.
- Video exports, photo libraries, virtual machine images and design files from projects you finished long ago.
- iPhone and iPad backups in `~/Library/Application Support/MobileSync/Backup`.
- Xcode's derived data, simulators and package caches, which can quietly grow large. See [developer caches on a Mac](/blog/developer-caches-mac/).
- Large Application Support folders left by apps you no longer use.

## From finding to freeing

Once you know where the space went, the right tool depends on what you found:

- Caches and logs belong in Clean, which knows each category's risk level and pre-selects only the low-risk ones. The [cache guide](/caches/) lists them all.
- An app you don't need belongs in Apps, which removes the app together with its leftovers in your [Library folders](/library/).
- Your own files are your call. Move them to an external drive, archive them, or delete them yourself.

When something does go through Freshist, the rules are the same everywhere: you see it first, and items from your user folder go to the Trash. Freshist won't move macOS system folders or your main personal folders themselves. The [safety page](/safety/) has the details.

## Before you delete a big folder

A treemap makes large folders easy to find, which also makes it easy to delete the wrong thing in a hurry. A few questions are worth asking first:

- Is it yours or an app's? A large folder inside `~/Library` usually belongs to an app, and removing it by hand can break that app. Removing the app with its leftovers is the cleaner route.
- Is it synced? Deleting a file in an iCloud Drive folder deletes it from your other devices too.
- Is there a copy? If it's a project you might need again, move it to an external drive or archive it before it leaves your Mac.
- Will it come back? Caches and build products are rebuilt as you work, so clearing them buys space for a while rather than for good.

## Seeing every folder

macOS hides some folders from every app until you grant it **Full Disk Access**. Without it, any disk analyzer will show less than what's really on your disk. The [Help page](/help/) explains how to grant it to Freshist.

## One license for the whole toolkit

Analyze isn't sold separately. It comes with Clean, Apps, Optimize and Status in a single license: $9 once, with lifetime updates, on up to 3 Macs, and a 14-day refund if it isn't for you. Scanning is always free. The app runs on macOS 14 Sonoma or later, on Apple silicon and Intel, and sends no telemetry.

## Frequently asked questions

### How do I see what's taking up space on my Mac?

System Settings › General › Storage gives you totals by category. To see which folders are actually large, use a disk space analyzer. A treemap shows every folder as a block sized by how much space it uses, so the biggest ones stand out straight away.

### What does hardlink-aware mean?

A hardlink lets the same data appear at more than one path. An analyzer that adds up every path counts that data several times and can report more space than your disk has. Freshist counts each piece of data once, so the numbers add up.

### Does Analyze delete anything on its own?

No. It shows you where the space went. When you decide something should go, you see it first and it goes to the Trash, the same as everywhere else in Freshist.

### Why doesn't my Mac's free space match what the analyzer shows?

macOS keeps some space that no folder view can show directly, such as local Time Machine snapshots and purgeable storage it frees when it needs room. Our guides to System Data and local snapshots explain where that space goes.

### Can I try it before buying?

Yes. Scanning is always free, and the free trial includes 2 cleans. A license costs $9 once and includes lifetime updates.
