I have this code,

What exactly are you trying to do with this? I get the impression 
that there is an attempt at "local optimization" when broader 
approach could lead to better results.

For instance. Using the OS's facilities to filter (six requests, 
one each for "*.doc", "*.docx") could actually end up being a lot 
faster.

If you could give more detail about what you are trying to 
achieve then it could be possible to get better results.
