Disk Space Analyzer & Cleaner

Phone storage full? Disk Optimizer is a disk usage analyzer and disk cleaner for Android. See what is filling your internal storage, find large files and free up storage in a few swipes.

Key benefits

• See storage usage at a glance: the disk space analyzer sorts used space into videos, APKs, images, audio and documents.

• Spot space hogs: the folder size analyzer ranks folders from largest to smallest.

• Delete large files with confidence: your biggest files come up front.

• Free up space and keep your originals: compress photos and videos into smaller copies.

• See which apps hoard space: check the app cache size of every installed app.

• Undo a wrong delete: removed files go to Safe Trash first.

Disk Usage Analyzer: see what is using your storage

This disk space analyzer runs a fast parallel scan to show your storage usage: how much space is used and what is taking it, with real sizes in MB and GB. Open any category, or use the folder size analyzer to drill down through folders sorted by size. Think of it as a storage analyzer that answers one question: where did my space go?

Large File Finder: find and delete large files

Big videos, downloaded APKs and old photos are often what leaves your phone storage full. The large file finder ranks them by size so you can find large files quickly, then open, move, rename or delete them. Start with the biggest files to free up storage with the fewest deletions.

Swipe to Clean

Your biggest photos and videos appear as cards, largest first. Swipe up to delete anything you no longer need. Want to swipe to delete photos? It works the same way and covers large videos too. It is a phone storage cleaner where you make every call.

Photo & Video Compressor

Compress photos or reduce video size for a whole folder at once to free up space. Choose images or videos, a quality level (High fidelity, Balanced or Compact) and a maximum size (original, 2048, 1080 or 720 px). Smaller copies go to an "optimized" folder and the originals stay untouched.

App Cache Size

The storage analyzer covers apps too: see app, data and cache size for every installed app, plus when you last opened it. A Clear All Caches button is included, though it may not work on all devices.

Who it is for

Why is my phone storage full?

Run the disk space analyzer and the biggest categories and folders appear first. Start with large videos, downloads and old APK installers to free up storage quickly.

How do I free up space without deleting apps?

Compress photos and videos, delete large files you no longer need, and check which apps hold the most cache.

Does it scan internal storage?

Yes, it works as an internal storage analyzer for your phone.

How do I find large files on my phone?

The large file finder lists them biggest first, and Swipe to Clean lets you review them one by one.

Is it a storage analyzer or a phone storage cleaner?

Both. It shows where your space goes, then works as a disk cleaner that removes only what you choose.

What makes it different

• Analyzer first: this Android cleaner starts with the disk usage analyzer, so you see real sizes before anything is deleted.

• You stay in control: the disk cleaner removes nothing until you pick it, and compression keeps your originals.

• Six tools in one app: Disk Usage Analyzer, Swipe to Clean, App Cache Size, Photo & Video Compressor, Folder Size Explorer and Safe Trash.
