How to open files in different folders for data processing?

Hello! I'm currently tasked with plotting data from several different files that are in different folders due to the way the data was processed. How can I script matlab to look through different folders and get a file (the file in each folder has the same name but the folders have different names) and grab the data that I am interested in?
I am very new to matlab so this is hard for me to try to do.
Thank you,
-Levi

Take a look at this.
It is possible to look through directories recursively with newer versions of matlab using the dir command, but the above should work for all relatively common versions in use.

@Levi: If you ask for details about my answer, please post them as comments to my answer.
The \*'*\ is the search string of the dir command means a recursive search in all subfolders.
Please take the time to look into th documentation:
help numel
The last character is an lowercase L, not a one.
You cannot learn the basics in the forum. The Getting Started chapters of the documentation and the "Onramp" (ask an internet search engine) are more efficient.
You can simply run the code and check, what the contents of the variable FileName is.

Since Matlab >= R2016b:
List = dir('C:\Your\Data\Folder\**\FileName.txt');
FileName = fullfile({List.folder}, {List.name});
for k = 1:numel(FileName)
disp(FileName{k})
...
end

"I wasn't aware of the ** being the command to search recursively, I thought it was a shortcut to basically say ..."
tip for the future: guessing how MATLAB works is very inefficient. Reading the documentation is much better (and if something is not clear, as Jan already wrote, you can ask us to clarify).
