Nexus USB OTG File Manager allows you to open and copy files from any USB mass storage device with a FAT32 or NTFS filesystem using the USB OTG port of your device, tablet or phone.

With a FAT32 filesystem, you can copy files to any USB mass storage device and manage your files on it (edit filenames, add directories, delete files) too.
You can also manage your files in the internal memory of your device.

This application has been designed for Nexus products which have an USB "OnTheGo" port, as the Nexus 5, Nexus 7 and Nexus 10, and the brand new Nexus 6 and Nexus 9. But it could work on any device with an USB OTG port Under Android 4.0 or later, including the last Android 5.0 Lollipop.

Root privileges are NOT necessary!

For now, FAT32 filesystem is supported for data read and write, and NTFS filesystem is only supported for data read. You can use USB sticks or SD card readers with any compatible USB OTG cable.


You can now play playlists (m3u and m3u8 files) and multiple audio files (mp3, aac, m4a, flac, ogg and wav files) at the same time from your USB OTG mass storage device. For that, you need to install my new app Simple Music Player which exists in two versions:
- Free version:
- Paid version to support my developments and get some additional features in the future:

Once Simple Music Player is installed, select the files you want to play on your USB device, push the open button and select the Simple Music Player app.
This is a brand new feature, so if you have any issue, don't hesitate to send me an e-mail! Your feedback would be appreciated too.

*** FEATURES ***

Nexus USB OTG File Manager allows you to open your files directly from your USB device! You just need to have an app that can handle it. For audio and video, I advise you to use VLC.
The new Network Access authorization is only here for local use to be able to open the files. The app NEVER send or receive data to/from Internet.

Nexus USB OTG File Manager supports devices with multiple logical units (like a GPS with an internal memory and an additional SD card) and allows you to choose which logical unit you want to read.

Nexus USB OTG File Manager now includes an "Advanced Mode" which allows you to access to all the files of your device. You can now create files and directories outside of the official Android public directories. This is for advanced users only!

Before buying this application, please try the free trial version named Nexus USB OTG FileManagerTrial to be sure that this application is working with your USB devices.

    I thought it would work for my nexus 5 based on the trial but......When I try opening a jpeg file, it goes to google photos, but then says no media found. For a PDF it says no app can open this file, when I hav adobe reader. Sometimes the app fails to respond.
