[vorbis] Why the commotion about file extensions?

[Jens Prüfer]

Hello all,

why is there all the commotion about file extensions? I do strongly believe 
any software using those extensions for identification of file contents is 
broken. After all, it is very easy to name a DivX Video .doc. Yet that ending 
changes nothing about the contents of the file. Word will complain about the 
content or (more likely) display a load of gibberish. More dangerously 
changing .exe or .com to .txt is also possible, smuggling in malicious code 
via email etc.

Instead an up-to-date magic file and truely looking at file headers is the far 
better way. Don't you aggree? I don't know, why this is not the standard way 
to do things. I guess, because Microsoft thinks looking at three letter 
extensions is good enough for them, it should be good enough for the rest of 
the world as well.

Cheers

Jens
