Data processing in MATLAB, searching over a large amount of folders

[C++ Programming]

Looking for a program that will search through a large amount of folders and sub folders and pick out certain information from .mat files in each.

Once the information has been pulled from the .mat files, be it the start time of the data processing, I would like the program to start building an array with the extracted information.

Any ideas??

I am able to extract the information that I want when I look for it directly in one specific .mat file but I cannot figure out how to set the program up to run through many folders and build a table of the extracted information.

HELP :/

Thanks in advance,
Martin
