OTG Nexus - USB File Manager

About OTG Nexus - USB File Manager

Read and rescue any USB drive on Android - Mac, Windows, and Linux, with no root and no PC.

Plug in any USB drive with an OTG cable and browse your files instantly, whatever format the drive uses. OTG Nexus reads more file systems than any other Android USB file manager, and goes further with a built-in kit to recover, image, and unlock drives right on your phone.

DRIVE RESCUE KIT

ENCRYPTED VAULT
Store sensitive files on the drive with AES-256 encryption, the vault stays on the drive and is never uploaded anywhere.

AUTOMATION
Auto-copy files when a specific drive is plugged in (per-drive, incremental, never deletes).

USB SECURITY SCANNER
OTG Nexus checks every USB device for potential threats:
- USB Rubber Ducky and BadUSB attacks
- Suspicious keyboard (HID) interfaces
- Rogue network adapters
- Unusual device configurations

BEAUTIFUL DESIGN
Material Design 3 with dynamic (Material You) colors, Light / Dark / System themes, and a clean, intuitive interface. No root required, works on any Android 8.0+ device.

PRIVACY FIRST
Your files stay on your device. OTG Nexus performs all file operations locally and never uploads your files, their contents, or filenames. To keep the app free we show ads (Google AdMob) and use Google Firebase for crash reporting and anonymous usage analytics; these may collect device identifiers, approximate location (from IP), app interactions, and diagnostic data. In the EEA/UK an ad-consent dialog appears on first launch and is editable from Settings. Remove ads with an in-app upgrade. Full privacy policy: obelisk.agency/otgnexus/privacy
