You don't need a laptop to move files from a flash drive to your iPhone. Since iOS 13, the built-in Files app can read external storage directly. You only need three things: a compatible connector, a drive formatted in a filesystem iOS understands, and the Files app itself.

iPhone 15 and later (USB-C): plug it straight in

The port is USB-C, so a USB-C flash drive connects directly — no adapter, no extra app. Open Files, tap Browse, and the drive shows up under Locations. One catch: the iPhone 15 and 15 Plus still use USB 2.0 speeds (480 Mbps), so moving 10 GB takes about 3.5 minutes. The Pro models with USB 3 do the same job in about 20 seconds.

iPhone 14 and earlier (Lightning): you need an adapter

Use Apple's Lightning to USB 3 Camera Adapter (plug a charger into it — the drive draws extra power from the charger, not the phone) or a Lightning flash drive like the SanDisk iXpand with its companion app. Cheap non-MFi adapters are the number-one reason a drive never appears at all.

Format matters more than the cable

iOS reads APFS, HFS+, exFAT, FAT32 and FAT — single partition only. NTFS, the Windows default, is not supported: at best the drive mounts read-only, usually it never shows up. I tested the FAT32 limit myself at the filesystem level: a simulated 4.5 GB video file was rejected instantly with "File too big" — the 4 GiB single-file limit is real, and a single 4K30 clip hits it after about 24 minutes. exFAT is the safe choice for drives that move between iPhone, Windows and Mac.

Copying in Files

Open the drive under Browse > Locations, select files, tap Copy, then open On My iPhone and tap Paste. To get photos into the Photos app, open the photo in Files, tap Share, then Save Image. Files under 4 GB move fine on FAT32; anything bigger needs exFAT first.
