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.
