See storage as boxes, then pick and clear big files and apps you don't use.
Read full description
See what's filling your phone's storage — without digging through Settings.
Boxsize shows the storage you're using as boxes the moment you open it. Videos, photos, your biggest apps and installed messengers each get a box. The bigger the box, the more space it takes, so you can compare at a glance instead of reading numbers one by one.
HOW IT WORKS
1. Open the app — the box view is the first thing you see, no menus in the way
2. Tap a big box — photos, videos, audio and downloads open as file lists, largest first, and you can select several and delete them at once
3. Tap an app box to jump straight to that app's "App info" screen and clear its cache
WHAT YOU CAN DO
• Compare the storage you're using as boxes, with a slim bar showing how much of the total is used
• See and delete just the photos and videos that messengers like KakaoTalk saved to your media folders
• Your biggest apps get their own boxes; every other app is listed by size under "Other"
• Cleanup routine — walks you through your 5 biggest apps one by one to clear their cache
• Unused apps — apps you haven't opened in a while, oldest first, with each app's recent access record
• This week — how much your storage grew since yesterday or the last few days
• Home screen widget — check the usage bar without opening the app
GOOD TO KNOW
• Seeing per-app storage and unused apps needs the "Usage access" permission — the app walks you through turning it on
• This app can't clear other apps' cache by itself. It takes you straight to that app's "App info" screen, where you clear it
• Messenger boxes show only files the messenger saved to your photo and video folders — not chat data or cache inside the messenger
• Deleted files can't be recovered. You'll be asked to confirm before anything is deleted
• Recent access records only go back as far as Android keeps them (varies by device)
• File contents never leave your device
• This app has ads. A one-time purchase removes the banner and interstitial ads
