Run a script for all subfolders

Hi

I have a script and I want to rut it for a folder. I should say that the folder has subfolders. The folder structure is like below:

'rocording\myproject\020320 (it is a date)\XYdata'

the first two folders are same but I have many folders for third subfolder (different dates) and one 'XYdata' folder inside each date folder.

I want to run my script for the text files inside the XYdata subfolders.

You can use the asterisk (*) as wildcard to generate a file pattern and the dir command to get a struct of all the matching files. Assuming we are in the directory where the rocording folder is located and your data are mat-files:

file_pattern = './rocording/myproject/*/xydata/*.mat';
data_dir = dir(file_pattern);
data_locations = fullfile({data_dir.folder}, {data_dir.name})

Then you can use fullfile to obtain a cell array of file locations. Now you can loop over this cell or use cellfun to do stuff with all the data.

Try this out,

mainDir = 'C:\Users\name\Documents\MATLAB\rocording\myproject'; % <-- replace with your real path
% Get a list of content 
content = dir(mainDir); 
% Remove content that isn't a subdirectory
subDirs = {content.name}';
content(~[content.isdir]' | startsWith(subDirs, '.')) = []; 

% Loop through each subdirectory
for i = 1:numel(content)
    % Create full path to the XYdata directory
    fullpath = fullfile(content(i).folder, content(i).name, 'XYdata');
    % Test that it exists
    assert(exist(fullpath,'dir')==7, ['Directory doesn''t exist: ', fullpath])
    
    % Use fullpath for your script.  
    % To add filename,   file = fullfile(fullpath, 'myFile.mat'); 
end

This is way more complex than it has to be. See my answer for the proper use of the asterisk as wildcard.

Thanks Adma, I got an error because 'XYdata' subfolder is second; before that I have the date subfolder ( XYdata).

The code runs but it say it could not find XYdata. (because XYdata is inside date subfolder).

@Boby S, What is the value of fullpath when you get the error?

@Benni, I do like your suggestion to use wildcards, it's robust, but I think you're overestimating the difference in complexity from my answer.

....\Ha\XYdata

The 'HA' subfolder exists but I do not have 'XYdata' in this folder.

Ah, if the subfolder structure isn't consistent then the wildcard method is the way to go.
