What is scoped storage on Android?

Last reviewed: September 23, 2026 · Markdown version

Scoped storage is why apps see less of your storage than they used to. Android's documentation says apps that target Android 10 and higher “are given scoped access into external storage, or scoped storage, by default”, and that such apps “have access only to the app-specific directory on external storage, as well as specific types of media that the app has created”. The stated goal is “To give users more control over their files and to limit file clutter” (Data and file storage overview, read 23 September 2026).

What an app gets by default

Two things: its own directory on external storage, and the specific types of media it created itself. For anything shared beyond that, the same overview names two routes.

"Shareable media files (images, audio files, videos)" go through the MediaStore API — and reading other apps' media there needs a storage permission.
"Other types of shareable content, including downloaded files" go through the Storage Access Framework — the system file picker.

That split explains a great deal of otherwise baffling app behaviour. The media-store guide tells developers that for files "such as files that use the EPUB or PDF file extension", they should use the document picker instead, and that "If your app wants to access a file within the MediaStore.Downloads collection that your app didn't create, you must use the Storage Access Framework" (Access media files from shared storage, read 23 September 2026). So an app that can show every photo on your phone but cannot find a PDF your browser downloaded is not broken — that PDF has to be handed to it through the picker.

What Android 11 tightened

Android 11 removed the thing most workarounds relied on: "Starting in Android 11, apps cannot create their own app-specific directory on external storage." For apps that target Android 11 or higher, it also closed the picker routes that used to grant a broad folder — the Download directory, the root of internal storage, the root of a reliable SD card — and blocked selecting anything inside Android/data/ or Android/obb/ (Storage updates in Android 11, read 23 September 2026). The full list of what went.

For apps whose purpose genuinely needs more, the same page names one route and scopes it: "some apps have a core use case that requires broad access of files on a device … Android provides a special app access called All files access for these situations." What that permission does and does not grant.
