SD Maid 2/SE is an app and file manager that knows which apps created files on your device. It compares files with installed apps to help you safely free up storage space.

✨ Clean up after uninstalling apps

If apps create files outside their designated folders then files can remain even after uninstalling the apps. The "CorpseFinder" tool finds app remnants, tells you to which app they belonged and helps you delete them.

🔍 Search your device the smart way

Filter for empty folders, temporary files, already installed apps and more. You can even create your own search criteria. The "SystemCleaner" tool automatically searches and deletes files based on various criteria.

🧹 Delete expendable files and hidden caches

Thumbnails, trash bins, offline caches and more: If apps don't clean up after themselves, then this app will. The "AppCleaner" tool finds apps with expendable files.

📦 Manage all of your apps

Get a comprehensive list of all apps installed on your device. Enabled, disabled, user or system app: no app can hide from you. The "AppControl" tool is an app manager that lets you search, sort and control your apps.

📊 What is using all your space

Storage management can be complex with apps, media, system, and other files across device storage, SD cards, and USB devices. "StorageAnalyzer" is a file manager that displays how space is used on your device, simplifying your storage management.

📷 Find duplicate data

Duplicate downloads, photos sent through social media or just similar pictures of the same scene: Over time copies can accumulate. The "Deduplicator" tool finds files that are exactly the same or similar and helps you delete extra copies.

👆 Declutter with a swipe

Pick a folder and go through files one by one with simple swipes to keep, delete, or skip. The "Swiper" tool lets you review all decisions before anything is deleted, and you can save a session to continue later.

🗜️ Save space without deleting photos

Photos can take up a lot of storage, but you don't always want to remove them. The "Media Squeeze" tool compresses your images with adjustable quality settings to free up space while keeping your pictures.
