removing heders of the file

00001 0xdfsd 0xrwe 0xdfg 0xds
00002 0xdfdf 0xddf 0xdfd 0xfdf
00003 0xdas 0xfsdf 0xdfd 0xfdf

Strange... Are that the literal contents of the file? Or are those supposed to be hex numbers (as the 0x prefix suggests)? If yes, what are characters like 'r', 'w' and 's' doing there?
