DiskState

DiskState helps you understand what's using space on your Android phone or tablet, review files before removing them, and manage folders on your device or a trusted SMB network share. SEE YOUR STORAGE Explore folder sizes with ring and block charts. Find the largest files and compare file types. Scan accessible device storage or choose a specific folder to keep the scope focused. Size scans read file metadata without changing your files. REVIEW BEFORE REMOVING Review large files, videos, photos and other cleanup candidates. Start an exact-duplicate scan when you want to compare file contents: DiskState uses SHA-256 and verifies matches byte for byte. Nothing is selected for deletion automatically, and each duplicate group must retain at least one copy. Similar-looking photos are not treated as exact duplicates. MANAGE LOCAL AND NETWORK FILES Use two panes to browse folders, open files and copy between supported local folders and SMB shares. Connect to your own server over a trusted LAN or VPN, and choose whether to save the connection securely. Follow transfers with progress and Stop controls. Hidden files are hidden from the browser by default. Recursive folder copies still include hidden files and subfolders, so a visibility preference does not silently leave them behind. Server permissions, Android access restrictions and supported file types still apply. UNDERSTAND APP STORAGE Choose to show your installed apps and review their storage sizes with optional Android Usage Access. Open Android's own app-management and uninstall screens when you decide to manage an app. DiskState does not remove apps without Android's confirmation. YOUR FILES, YOUR CONTROL No ads, analytics or DiskState account. File analysis and duplicate comparison run on your device. Network file operations go to the SMB server you choose. Android permissions and special access are explained before use. Selected-folder mode works with the folders you grant access to. Broader shared-storage scanning requires All files access on supported Android versions. Protected app and system data remain inaccessible. DiskState is MIT-licensed, donation-supported freeware. All features are available without a payment. IMPORTANT Back up important files before cleanup. Deleting files can be permanent, and a duplicate may be an intentional backup. Reported sizes are logical file sizes, not a promise of recovered storage. Review each action before confirming it.
