I worked with IBM PC clones and DOS for a long time. What I seen - just hexadecimal dumps, sometimes picture patterns and nearly nothing else. Once one boy said me "this is Mac, on it things look different" and shown me just ordinary MS Office (for Mac) files in just standard utility. And I seen really other world - even on old MacOS (7..something), Office files was not just hexadecimal, but I easily see structure. Unfortunately, that's time I have not enough education in CS to understand how structures work, but some things was obvious. These was just some things partially implemented on ObjectiveC (too small objective part and too large C part), but any way it become significant shake of my world. Unfortunately, in Linux I constantly see the same as in DOS - mostly just hexadecimal dumps, no structure, so developers don't have motivation to use structured data, as it will not help them on build and maintenance.
