My project consists of me reading the contents of a folder. The folder 
will have 5 files for testing. The files are named as such...

AUR234_somename.txt
PUR233_somename.txt..

If a file starts with AU I know that this file fits the Aero group and 
the third letter being 'R' tells me if it is registered. If a file fits 
the condition. I want to store that filename so that other programs can 
peform I/O tests on it. The 5 files will be replaced occasionally but 
with the same strict naming conventions. Each file will be meant for a 
different type of test. The number represent a count that will be 
validated later in the test as well.

Good tip- I will apply lowercase letters to the filenames. I don't think 
the partition will help in this case though. Thanks -MC
