How to check storage on Mac

It’s good to check your storage details before we get down to deleting things. For example, this my disk space structure:

Well done!Now you can type in different file extensions and sort the results by size. I recommend starting with the .DMG files or application installers. They are just dead weight and you can live without them. The same goes for .ZIP archives


After you run the Scan, review the files and click Clean.

What else can you delete with this tool:

Time machine backupsTemporary documents versionsOutdated system logsApp localization files

3. Remove unused apps and all their leftovers

Potential space reclaimed: up to 5 GB

Did you know there are 3 ways of deleting apps on Mac? One is dragging them straight to the Trash from Applications, the other involves Launchpad. And, finally, you can use a third-party Uninstaller tool, which also makes sense because the first two methods leave parts of old apps on your drive.

Delete apps via Launchpad

Still, I prefer deleting apps via Launchpad because it’s more fun. Open Launchpad from your Dock.Now, press the Command key and hold any app icon until they start shaking. You will see the symbol above the icon — click it to delete the app.

From there you can delete apps on a massive scale – simply select the ones you don’t need. Make sure to check the Leftovers section. These are parts and pieces of your old apps that you can’t otherwise access.

4.Delete your duplicate files

I often download an app twice by clicking on it several times or double-save a track to my iTunes library, which creates quite a mess. So if your Mac has started to run out of storage, there is a way to put an end to it. At first, you can try to find duplicates manually, but it can take you way too long with little to no result.

There is a good app called Gemini 2 – the duplicate finder. It allows you to clean out many gigabytes of duplicates in a few clicks. Plus, it allows you to check what would be deleted and deselect items you want to keep.


So, if your Mac is suffering from the invasion of the duplicates, give this software a try.

5. Remove browser cache

If you are a heavy internet user (like I am) your Mac’s drive is full of the browser cache. These are kinds of bookmarks left on your drive by every site that you visited. What’s your primary browser? Here are the solutions for Chrome and Safari.

To clear Chrome cache

While you are in Chrome,

Click the three-dot icon at the top rightClick More tools > Clear browsing dataChoose a time range to clear the browsing dataAlso, clear “Cached images and files.”


6. Use Optimized Storage

This may help you free up a couple of gigabytes. When you need to clear disk space on Mac, every little helps.

9. Delete extra language files

Potential space recovered: 1 GB

There are 180+ languages in the world and most of your Mac’s applications can operate in these languages. However beautiful the language diversity is, people usually use just one or two. When you need to clear space on Mac, extra localization filesare another target.How to see your language files? Language files end with “lproj” extension, which stands for “language project”. Unfortunately, finding them manually is problematic. Still, if you want to recover 1 GB of free space out of thin air, get hold of CleanMyMac X. It deletes extra localizations automatically.
