Solved! Managing music files in a portable player

[sadhak61]

I have this Philips Portable Speaker Model AT10/00 which can play music direct from USB. A 32gb USB can hold so many folders with each of them loaded with hundreds of MP3 files.
How can I make the player select the folder I choose and play the mp3 files in the sequence I set?
I try to manage by using Bulk Rename Utility to remove and revert the file extensions.
Is there a better way?

Looking at the manual, I see no way to select folders and/or order of playing. Why not ask them directly?
