WRITE_EXTERNAL_STORAGE	API ≤ 29	Write, move, rename, and delete files on internal storage and SD card
MANAGE_EXTERNAL_STORAGE	API 30+	Broad storage access on Android 11+, where the legacy read/write permissions no longer apply (required to browse and manage all files outside of app-specific directories)
