The 'file' command and mime types are different things.

If you do a 'file something.ppt', I am fairly certain it will also say
Microsoft Office Document. While grepping for 'Excel' and 'Word' both
turn up some stuff in /usr/share/misc/file/magic, there isn't anything
that corresponds to 'Power' except for PowerPC related stuff. 

In fact, I am pretty sure that documents from newer versions of
Microsoft Office would all return that string when file is ran against
them.

The question is how you are recognizing the files? From what you are
saying, it sounds to me like you are double-clicking in some KDE file
browser and letting KDE do the job of deciding which application to
call. Since I know naught about KDE, I can't help there.

However, one thing that came to mind is for you to check the
mime.types file in /etc/mime.types and make sure

[01:01 PM]wwong ~ $ grep pps /etc/mime.types
application/vnd.ms-powerpoint                   ppt pps

pps files are indeed associated as powerpoint.
