i-FlashDevice

1. Download the app, connect your i-FlashDevice or compatible external drive to your iPhone or iPad, and allow access to Photos, Contacts, and Files when prompted. 2. Set up preferences: choose default backup folders and create a passcode if you want encrypted storage. 3. Back up core data: tap Backup to save Photos, Videos, and Contacts to the external drive, and confirm completion in the progress view. 4. Transfer and manage files: open Files, select items, tap Copy or Move, then choose Phone, External Storage, or Cloud; rename, sort, and delete as needed. 5. View and share: play videos and music directly from the drive, open documents in the viewer, or share via AirDrop, Mail, or other apps; enable Auto Backup in Settings for hands-free syncs.
