Windows 7 How to View and Modify PRP Files from a USB MP3 Player?

[Cardinal System]

I have a little USB mp3 player that I wanted to experiment with, so I copied the hidden files that operate it to my desktop then ejected it. I wanted to view the code operating it, find out what programming language it used, and possibly modify it. It's files were of type PRP, which I have never seen or heard of before. I can't view them with notepad. Is there a program that can view and/or edit/decompile PRP files?

Here is a download link to all three files, if it helps you in anyway. MediaFire

they are a type of image file... any of the older photo editing software that can open gimp or Tar files should handle these as well

Could you suggest a free downloadable editor?

gimp

I tried gimp, instead of opening it, it said "Unknown file type" :/

How about opening it in a hex editor like HxD?

Well, that did open it, but it seemed to be written in raw binary code. :/
I guess there is no point trying to modify this, because binary is way out of my world.

Well everything is binary. After some googling, these seem to be property files associated with gimp images. There really isn't any reason to try and modify these
