I have a few other files(20090101.csv, 20090102.csv, and 20090102.csv).
What's the difference between 20090102.csv and 20090102.csv ? [That is, why is the same file specified twice, as confirmed by your header Number,20090101,20090102 ,20090102?

Showing us the code you wrote is more likely to help you (by possibly fixing the problem) than by simply giving you the answer.
