Features
Read full description

A-DISK is a local file manager and backup tool. No account is required, and your files do not need to be uploaded to a cloud service. KEY FEATURES • Browse, copy, move, rename, delete, and organize files and folders • Add a USB drive, iCloud Drive, or another external location with the system Files picker • Back up and restore photos, videos, contacts, and documents • Preview images, videos, audio, and text files • Protect files with Secure Encryption or Fast Lock • Save photos, videos, and recordings to the location you choose • Protect the app with a launch password and biometric authentication iOS EXTERNAL STORAGE On iPhone and iPad, A-DISK uses the system file picker so you can explicitly authorize a folder. Without a physical drive, you can select a test folder in Files and use the same workflow. iOS does not provide a general App Store API for directly ejecting a USB drive; disconnection is managed by the system Files app. PRIVACY File processing takes place between your device and the locations you authorize. The current version contains no advertising, behavioral analytics, cross-app tracking, or cloud upload service. See the privacy policy for permission and local-storage details.
