Storage Analyzer
The Storage Analyzer breaks Mac disk usage down by category and folder so you can see exactly what is consuming space before you delete anything.
Short answer
The Storage Analyzer shows how much disk space each category and folder on your Mac is using, so the largest consumers are identified before any cleanup begins.
The Storage Analyzer is a feature of Neatwise: Mac Cleaner, a macOS utility distributed through the Mac App Store.
The Storage Analyzer reports disk usage per category and per folder rather than as a single total.
What the Storage Analyzer does
The Storage Analyzer answers one question: where did the space go? It reports disk usage for the categories and folders on your Mac, ordered so that the largest consumers are visible immediately.
Without it, the usual approach is to open folders one at a time and use Get Info on subfolders, guessing which branch of the tree is responsible. The analyzer replaces that with a single report.
How it works
The analyzer walks the volumes it has been granted access to and aggregates the sizes it finds in two ways:
- By category, so you can tell application data apart from documents, media and system files.
- By folder, so you can tell which directory inside a category is responsible.
Both views matter. A category total tells you that application data is large; a folder view tells you which application’s data it is.
When to use it
Use the Storage Analyzer first, before any cleanup. Removing files without knowing what is actually occupying the disk is how people end up deleting something they needed and keeping the thing they did not.
It is also the right tool when the numbers do not add up — when macOS says the disk is full but you cannot see what filled it.
Reading the results
A large category is not automatically a problem. Some of what you will see is expected: caches exist to make applications fast, and system files exist because macOS needs them. The analyzer’s job is to tell you the size of each thing, not to decide whether it should exist.
The useful question is not “what is big” but “what is big and I no longer need”. Answering that usually means following the analyzer’s results into the Large File Finder, the Duplicate File Finder or the Junk Cleaner, depending on what the report shows.
What the Storage Analyzer does not do
- It does not delete files.
- It does not decide which files are safe to remove.
- It does not report a single “you could free X” figure, because that number would be a guess rather than a measurement.
Where it fits
The Storage Analyzer is the first step in the sequence described in What Is Taking Up Space on My Mac? and the wider How to Free Up Storage on Mac guide.
Frequently asked questions
- How do I see what is taking up space on my Mac?
- Open the Storage Analyzer. It lists the categories and folders on the disk alongside the amount of space each one occupies, ordered so the largest appear first. That list is the starting point for deciding what to remove.
- Why is the free space reported by the analyzer different from what macOS shows?
- macOS reports free space after accounting for purgeable space, snapshots and system reservations. An analyzer counts actual file data. The two figures can differ, and the difference is usually purgeable or reserved space rather than a measurement error.
- Does the Storage Analyzer delete anything?
- No. It only reports. Deletion happens through the cleaner, the finders and the uninstaller, each of which asks you to confirm.
- Can the Storage Analyzer scan an external drive?
- The analyzer works on volumes it has permission to read. If a volume has not been granted access, macOS will ask before it can be scanned.
