The best storage analyzer to free up space on Mac.

Is your disk running out of free space? Don’t rush to buy more storage or a new disk! First, clean up your hard drive with our Mac disk analyzer.

Unused files might be taking up a significant amount of your HD space. When your Mac startup disk is full and you have a low memory space, use the drive space visualizer to view your Mac disk usage and remove unused stuff from your computer.

Use Disk Space Analyzer to:
• Analyze disk space on Mac
• Get your disk usage visualization
• Find out what is taking up space on your Mac
• Detect unused files and folders
• Move rarely used bulky content
• Remove files and folders you don’t need
• Easily navigate through folders directories
• Keep your Mac startup disk clean
• Clean up your Disk in minutes

This Mac Disk Space Analyzer allows you to locate the biggest files and folders that eat up precious hard drive space. The application scans the disk file structure, analyzes the remaining disk space and represents your files and folders with an intuitive sunburst-like diagram. Bigger folders are visualized larger in the diagram, making it is fast and simple to find the bulkiest data and make a disk cleanup.

Disk Space Analyzer can scan all types of volumes:
▹ Hard Disk Volumes
▹ SSDs, CD and DVD disks
▹ Flash drives
▹ External storage disks
▹ Mounted DMG volumes
▹ and even folders with FileVault protection

The Mac disk analyzer provides a visual scanning mode, and results of the scan are shown in real time. You can view a small progress bar on the dock icon which displays the scanning progress. For every disk item, the utility provides a QuickLook Preview, a possibility to get an additional detailed information and view the item in the Finder.

Best features:
◇ Progress bar during scanning process
◇ The ability to navigate folders during the real-time scanning
◇ Detailed information about the disks, files, and folders
◇ Quick Look for the scanned items
◇ The Open in Finder option
◇ Creating a list of unneeded items
◇ Copy path for the items
◇ Operating the items
◇ Displaying the folders structure
◇ Displaying even hidden files and folders
◇ All drives support

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

Use the application to view each folder size and find out what is taking up your Hard Drive space. Moreover, you can obtain the additional information for every disk: whether or not the disk is writable or bootable, the file system type and the disk’s connect protocol.

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!

It is an okay program I used it just a few minutes back.

It does what it advertises; cleans the disk in few clicks. Here's the catch. it asks you to back up before going forward with disk clean up. You will learn you should. It cleans up
the files in your download folder. It says download in the (first screenshot above) also in your report if you have anything in your downloads folder. I use download folders as temporary storage folder. For example if I receive a document with comments that I need to work on. I open it form there and work on it. Once am done correcting I will save the file in the actual folder in the documents where ever it belongs, and this app cleaned the downloads folder. Fortunately. I did not have any pending paper right now. The app should say which folders it is going to clean up.

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.
