USB OTG File Manager for Android
Plug a USB flash drive, SD card adaptor, or external hard drive into your Android phone via USB OTG — AnExplorer detects it instantly and gives you full read/write access without any setup.

No app configuration needed. Android's USB OTG storage mount is handled automatically. The drive appears under USB Storage in AnExplorer's sidebar once plugged in.
Move Large Files Without Cloud
Camera backups, game OBBs, project files — move them from phone to USB drive (or vice versa) at USB 3.0 speeds with no internet and no cloud costs.
Copy Between OTG and SD Card Directly
Select files on the OTG drive → Copy → navigate to the SD card → Paste. Files move on the device without involving internal storage — ideal when internal storage is nearly full.
