Run a script on all files in a folder/subfolders

I presently have a script which uses uigetfile and multiselect to grab several files in a folder and then loops through them; writing them to a table, getting averages of some variables, and then writting those averages to another table with the original filename as a column. The resultant table is then written to a csv after the loop completes. However, I have many folders with this particular type of file and they are separated by a few different parameters in subfolders (month, date, event name, etc.).

Is there a function which I can use to search a particular directory and all subfolders for files with names that meet my criteria? There is a common string in the filename which I can search by, ex. *filetype*.csv. I have used the dir command to return all files that meet the criteria to the command window but I cannot save them to an array with their respective path in column one and the filename in column two. Whenever you try to assign the dir output to a variable it uses the third option of the dir command to extract file attributes rather than names. I may be missing a function which does what I want already but I haven't found it.

example folder structure:

myfolder_2022

jan

event1

xxxxx_filetype_xxxx.csv

feb

mar

event2

xxxxx_filetype_xxxx.csv

aug

event3

xxxxx_filetype_xxxx.csv

I think the approach here can be used.

Yes, this ultimately worked for me after some tweaks and other searches Can you use DIR to list files in subfolders ? - MATLAB Answers - MATLAB Central (mathworks.com)

Thank you

x_path=uigetfile('X/XY/')
file_info=dir(fullfile(x_path,'**','*file_string*.csv'));
filenames=fullfile({file_info.folder},{file_info.name});

I was then able to iterate through the filenames with my script.

..some example lines of code using .net System functionality

import System.IO.*

searchDir = "C:\Temp";

pattern = "*.*";

searchOption = System.IO.SearchOption.AllDirectories;

fsEnumerableIterator = Directory.EnumerateFiles(searchDir, pattern, searchOption);

enFilesFound = fsEnumerableIterator.GetEnumerator;

while enFilesFound.MoveNext % set up data collector

fileFound = enFilesFound.Current;

dInfo = DirectoryInfo(fileFound);

dInfo.FullName % access DirectoryInfo struct

fInfo = FileInfo(fileFound);

fInfo.FullName % access FileInfo struct

end
