Plotting Large data in multiple files.

Hi, I have been experimenting with LabView which generates large dataset. The dataset contains
- 28 files
- Files 0001-0009 contains 3 columns (Sound Pressure, Acceleration, Acceleration_0)
- Files 0010-0028 contains 4 columns (Time, Sound Pressure, Acceleration, Acceleration_0)
- Each file has 65500 rows.
- Here Time column in File 0010-0028 has no use.
I have to get Fast Fourier Transform (fft) of the 3 columns (Sound Pressure, Acceleration, Acceleration_0). What I'm thought of doing is to create a script which reads in loop and does all the above work. But the loading of data takes too much time. I have read some answers which suggest using datastore and map reduce, but I have no idea how to use that to plot 'fft' for all the data in the below linked data set.
Please help. Thanks in Advance
