> I am getting many files being incorrectly detected as application/x-emf. I think the current magic is too common. According to MS documentation (https://msdn.microsoft.com/en-us/library/cc230635.aspx and https://msdn.microsoft.com/en-us/library/dd240211.aspx), it can be improved to:
> {code}
> <mime-type type="application/x-emf">
>     <acronym>EMF</acronym>
>     <_comment>Extended Metafile</_comment>
>     <glob pattern="*.emf"/>
>     <magic priority="50">
>       <match value="0x01000000" type="string" offset="0">
>       	<match value=" EMF" type="string" offset="40"/>
>       </match>
>     </magic>
>   </mime-type>
> {code}
