The identifiers from your program are the debugging info.  You can strip 
them (and make the image slimmer) with the strip.exe program, like this:

	strip myprog
	coff2exe myprog

The parts which seem like a directory structure are just a slack space 
which DJGPP uses to make your image size a multiple of 4KB (presumably it 
would then load faster).  It is just filled with the first available 
junk, so you don't have to worry about that.
