Every once in awhile you come across an app and wonder, “Why haven’t I been using this all along?” That’s what happened when I discovered Disk Usage & Storage Analyzer for Android. This tool will easily keep track of what is gobbling up precious space on your mobile device.

Anyone that has found their smartphone dangerously full knows how helpful an app like this can be. Yes, Android has a built-in tool for this purpose, but it’s not exactly helpful. If you want to really get granular and interact with files, you need Disk Usage & Storage Analyzer.

Say, for instance, your device is full, and you not only need to know what’s eating up that space, but require a quick way to delete files to make room. Disk Usage & Storage Analyzer is what you need. Let’s install this app and see just how it can help you recover space on your Android device.

Installing Disk Usage & Storage Analyzer

There are two versions: Free and Pro. The Pro version is $2.99 USD and allows you to see the /data folder, gives you even more granular detail, and lets you customize the colors used.

Follow these steps to install the app:

  1. Open the Google Play Store on your Android device.
  2. Search for disk usage & storage analyzer.
  3. Locate and tap the entry by Mobile Infographics.
  4. Tap Install.
  5. Read the permissions listing and, if you find them acceptable, tap Accept.
  6. Allow the installation to complete.

Once installed, you’ll find a launcher labeled Drives on your home screen, or in your App Drawer, or in both spots.

Using Disk Usage & Storage Analyzer

When you launch Disk Usage & Storage Analyzer, it will very quickly analyze your device and report back what it finds (Figure A).

You can check out the different tabs for the various reports, but if you want to get serious, swipe to the right until you land on the FILE CATEGORIES tab (Figure B).

Getting ready to delete some files in Disk Usage & Storage Analyzer.

In this tab you can see which categories are taking up the most space and then navigate into those categories and start deleting files. But if you want to quickly get rid of the largest files on your device to make more room, do the following.

  1. Tap the overflow menu (three horizontal lines in the top left corner).
  3. Tap TOP 10 (in the Pro version you can examine TOP 50 and TOP 100).
  4. Scroll through the listing of the largest files (Figure C) and long press one you want to delete (if you just tap the file, it will open).
  5. Tap the Trash can icon that appears at the top.
  6. When prompted, tap OK to delete the file.

What’s missing?

Unfortunately, the only thing missing from Disk Usage & Storage Analyzer is the ability to delete in batch mode. So if you have a lot of larger files you want to get rid of, you have to do it manually… one at a time.

Even with that one caveat, this is a must-have app for Android users who struggle to free up space on their devices.
