Step 1 - Add a Media Section if you haven't created one already.
Step 2 - Click within the section
Step 3 - Click Add Media
Step 4 - Drag and drop the file or upload from computer
Keep in Mind:
- If the name on your media file contains characters special characters (basically, any symbol you see over your numerical keys) your file will not be able to be uploaded to the player. Try to keep your file names as simple as possible, using mostly numbers and letters, to avoid any issues.
