I don't know how to upload anything to my Blusens MP4 player... HELP!

If you include the model of it then you might get a better answer or even a manual for it online.

If it shows up in "my computer" then check if it has folders. Those folders are where your files would go and then it's a matter of drag and drop. Then when you use it you should be able to play them back.

Copy and past it into your player, it is easy.

Thank you. It's a blusens mp4 player. I will have to do this once I get a new laptop. Thanks all.
