Well, it's a computer, you should not have to watch anything ....

I will first admit that 6.5 million files is substantial, beyond my 
experiences.

You could devise some procedure to access files and also monitor CPU 
usage.  Set it up to report only positive hits.  This just might give 
you a smaller subset of files to consider.  Then again, the problem 
might be elsewhere, and every file might cause the same CPU usage.

Don't know your application, so this suggestion may not be feasible.  If 
it was my problem, I'd just get some large storage for the VMS system 
and store everything there.  However, if some services occur off the VMS 
system, this would not be a solution.  Nor does the suggestion address 
your question.
