Five years ago that worked with my son's Creative player. He never used their software.
Did you try already with yours?

I have a Creative mp3 player which I dont find very user-friendly when it comes to organising sound files (I use this one for birdwatching; not for music).
Can anyone recommend a mp3 player which uses simple drag n drop (Windows explorer style) for organising files? I would like to create my own folders and the just bulk-drop files from my computer into these folders.
