Disk Inspector

By Nektony

Open the Mac App Store to buy and download apps.


Disk Inspector is a utility that allows you to locate "space eaters" - big files and folders saved on any of your Mac disks or drives.

Do you have any finishing free space on your disk? Thinking about buying a new disk? Hold on before you do. First, remove any unused stuff from your computer. Use Disk Inspector to find the biggest files on your Mac, and remove the unused files!

To do that, it scans the disk file structure, and shows your files and folders on the disk in a sunburst-like diagram. Bigger items are bigger on the diagram, so it's really easy to find bigger ones.

Disk Inspector allows you to scan: Hard Disk Volumes, CD and DVD disks, Flash drives, External storage disks, mounted DMG volumes, and even folders with FileVault protection!

Disk Inspector has a visual scanning mode, so that you can see the results even during the scan process. There is a small progress bar on the dock icon to show the current progress.

For every disk you can obtain additional information about it: if the disk is writable, bootable, the file system type, and connect protocol. For every disk item, you can use QuickLook Preview, get additional detailed information, and show the item in Finder for operating it - to delete or move unused files.

Note: All hidden files are displayed as a single item in the diagram.
If you need to preview even system hidden files & folders use our advanced clean up scanner - Disk Expert (see a link in “More Developer’s Products").

Incredibly Easy to Use and Effective!

I don't usually write reviews but I felt compelled with this little gem of an app. If you want a fast, comprehensive breakdown of where exactly your disk storage is coming from, look no further! The interface is very user friendly, one click to scan. The color breakdown makes it quite easy and straightfoward to nail down where your problems in storage hogging media / applications may lie, and it allows you to easily navigate through the folder heirarchies with seperate color, pinwheel diagrams.

What this does, it does extremely well. It's a steal at $2.99 on the app store right now. Already paid for itself. Personally I nailed down 50 GB of unndeeded disk hogging right after my first scan. Doesn't explicitly say in the description, but it does work with SSDs no problem.

If you want to know exactly what is taking up space on your harddrive in a streamlined, easy to use and asthetically pleasing manner, look no further. Recommended!

no hidden files

This app would be perfect if it showed hidden files. The explanation in the help docs is that it "Does not show you hidden files and folders for stability reason. It's possible to delete system files and folders if user is new to Mac OS X, better just not to display them.” is annoying. If you’re actually worried about that then provide an option to show them. Somewhere burried in the hidden files in my home directory is 12gb of wasted space, too bad I can’t find it.

Other than that one very big issue this app is great. Its fast, has a great interface that lets me drill down quickly and find problems.

I’m a web developer so I often deal with big databases, applications that cache data and I forget to clear it, or big virtual machines I forget that I have created. This app finds all that and finds it fast. Thanks. Please just display the data for my hidden files too. At least the ones in my home directory.

New to Mac….I appreciate this app.

I recently purchased a MBP retina with a 500Gig SSD. It’s my first venture into the fray of the world of Apple (which I have wanted to do for years). I have had a bit of a time switching over and it seems that file navigation is my number one issue. This app really lays it out in an easy to understand (and find) format. Because my Mac is less than 2 months old, the app really didn’t find any hidden ‘hogs’ that I didn’t know about, but I can see the true value in this app and appreciate the intuitive ‘wheel’ it uses so you can really home in on what’s using up your storage space.

I recommend this app to anyone who wants a very fast and accurate breakdown of what and where is on their storage device. Well done!
