If you do not want to learn the admin workflow first and only want to copy files to a USB drive and play them on the device, start with this method.
Before you begin, make sure:
- The Player app is already installed
- The images, videos, or other media you want to play are already copied to the USB drive
- You accept updating content by manually going to the device and plugging in the USB drive
Step 1. Install the Player on a TV, set-top box, or signage device
Choose the installation package that matches your device's hardware and operating system.
Make sure the Player app is already installed. If not, obtain the correct installation package from your current download or distribution channel.
After the setup completes, launch the app and you should see the screen below. 
Step 2. Enable USB playback
Turn on the USB Playback feature. 
Step 3. Insert the USB drive
After you plug in the USB drive, the system displays the dialog shown below. 
Choose either Copy & Play or Play Directly.
- Copy & Play copies the USB content to internal storage so playback continues even after you remove the drive.
- Play Directly plays the content from the USB drive; playback stops once the drive is removed.
If this is only a temporary on-site playback and the USB drive will stay plugged in, choose Play Directly. If you want to copy the content first and then remove the USB drive, or let the device keep playing on its own later, choose Copy & Play.
If the dialog does not appear, the device may not support USB detection.
If the USB content cannot be read, confirm the Player has storage permissions.
Monitor the playlist and remove any items that are not playing as expected. 
If the playlist already shows the content from the USB drive and playback has started, USB Disk Play is working successfully.
