“What the hell is filling up my hard drive?” It’s a question we all have after a year or so of downloading files and storing work documents on our Macs. A cluttered storage disk can lead to all sorts of problems, not the least of which is making your Mac run slow.

CleverFiles has a fairly new app for Mac OS X that can help you analyze your storage drive and remove large files and folders easily. Disk Cartography maps your drive data and lists the space-hogging files in an easy-to-read list, and allows you to delete the unwanted files/folders with the click of a button.

Upon launching Disk Cartography, it scans your chosen disk and displays a tree-like folder-structure which you can use to evaluate what’s taking up space, as well as where it is on your drive.

You can manually or automatically filter what is shown by setting parameters such as minimum file size, or whether or not to show System files, etc. The minimum file size feature is particularly useful because it allows you to view your file folder list without the thousands of files taking up so little space that it’s not worth seeing. You can see an example in the image above. Those “Filtered Objects” folders contain all the files on my drive that don’t meet my minimum filter requirements of a minimum of 128MB in size.

Scanning my drive took only a few minutes, and the app displays the data in a clear and simple interface. I also liked that I can right-click on a file or folder to ‘show it in the Finder.’

Disk Cartography isn’t the only app out there that does this, and it certainly doesn’t have the most luscious user interface of them. But I like the simplicity of the app.

There is no dedicated web page for Disk Cartography as of this writing, but you can buy it directly from the Mac App Store here.

You can grab your copy for $1.99 until May 18th when the promo ends.
