How file extensions ruin the understanding of normal users……

One of the big differences of Windows and Linux is, that Linux mostly does not care about file extensions , which windows does. First, I thought that file extensions specifiy directly the type of a file, so that programmers do not need to care if it’s of the right type, but in the last time some of my friends ask m, why there selfconverted audiofiles don’t work. I first asked them what tool they used and they usally answered: “I just changed the file extension from wma to mp3″, which of course just makes a file ending on mp3 with wma-data in it. This would work in most cases under Linux and Windows too, but what if they change .sh to .exe, no problem under Linux(where the shell-script is still executed), but Windows would say, that it’s not a correct executable und just stop trying other cases.
