Browse USB Drives and Network Shares in Files
iPhone can connect to USB flash drives, SD card readers, and network file shares through the Files app, letting you browse, copy, and manage content directly from connected external storage.
How to open External Storage (Files App)
- Connect a USB drive using a compatible adapter, or open Files → Browse → Connect to Server for a network share
- Enter server credentials if prompted
- Locate the new volume under Locations in the Files app
- Browse, copy, or move files as needed
- Eject the volume properly before disconnecting hardware
What you should know
- Supports USB drives and card readers via a USB-C to USB or Lightning adapter
- Network shares (SMB) can be added as locations under Files > Browse
- External volumes appear as locations alongside iCloud Drive and On My iPhone
- Files can be copied between external storage and on-device or iCloud locations
Why it matters
The Files app's support for external storage turns iPhone into a more capable tool for offloading photos and videos from a camera's SD card, transferring files without relying on cloud sync, or accessing documents stored on a home network drive. This matters most for professionals like photographers and videographers working in the field, or anyone needing to move large files that would be slow or costly to sync through iCloud. It closes a long-standing gap between iPhone and traditional computers for basic file management tasks.
Best practices
- Use a certified USB-C or Lightning adapter to avoid connection reliability issues
- Safely eject external drives from the Files app before physically disconnecting
- Add frequently used network shares as Favorites in Files for quick access
- Copy large media files to on-device storage before extended offline editing sessions
Common problems and fixes
- A USB drive isn't recognized
- Confirm the adapter and drive are compatible with iPhone's supported formats (e.g., exFAT, FAT32)
- A network share won't connect
- Verify the server address, credentials, and that the device is on the same network under Files > Browse > Connect to Server
- Files transfer slowly from external storage
- This can be limited by the adapter or drive speed rather than iPhone itself
Tips and tricks
- Use the Files app's search to quickly locate content across both external and cloud storage locations
- Tag important files in Files for faster retrieval later regardless of storage location
