- Confirm your USB drive or external hard drive meets Apple's requirements. If your flash drive doesn't meet these requirements, you won't be able to access its files on your iPad:
  - The USB drive must only have a single data partition formatted as APFS, APFS (encrypted), macOS Extended (HFS+), exFAT (FAT64), FAT32, or FAT.
  - If you're using an external drive that doesn't supply its own power, you'll need to use a powered USB hub (USB-C). If your iPhone has a Lightning port, use the Lightning to USB 3 Camera Adapter connected to a USB power adapter.
