MATLAB: List of all subfolders and theire subfolders etc.

directories

Hello everybody,

I have a directory and I want to create a list that contains the paths of all subfolders within that directory and all subfolders within every subfolder in that list and so on.

I'm actually looking for specific folders that contain a number of specific files. The directory I'm working on has x amount of "layers" of subolders. I tried to use a recursive function to get those specific folders but I can't quite make it. So my second approach is just to get a huge list of every folder (including all subfolders, theire subfolders, and so on…) and its path within my main directory and then in a second step check everyone of those folders individually for these specific files.

Is there a way to get all those folders within a directory? I've got the feeling I'm missing an easy approach here.

Thanks alot in advance!

Yes. list=dir('**/*.*') will do it. Then check for list.isdir

MATLAB: Read Only files (from a directory) that contain a specific string in filename

This will do it:

folder = pwd; % The current folder, or else wherever you want.
% Get a list of all files.
fileList = dir(fullfile(folder, '*.*'));
allFileNames = {fileList.name}
% Define what pattern you will need in your filenames.
pattern = 'B10';
numFilesProcessed = 0;	% For fun, let's keep track of how many files we processed.

for k = 1 : length(allFileNames)
	% Get this filename.
	thisFileName = fullfile(fileList(k).folder, allFileNames{k});
	% See if it contains our required pattern.
	if ~contains(thisFileName, pattern, 'IgnoreCase', true)
		% Skip this file because the filename does not contain the required pattern.
		continue;
	end
	% The pattern is in the filename if you get here, so do something with it.
	fprintf('Now processing %s\n', thisFileName);
	numFilesProcessed = numFilesProcessed + 1;	% For fun, let's keep track of how many files we processed.
end
fprintf('Done running %s.m.\nWe processed %d files with %s in the name.\n', ...
	mfilename, numFilesProcessed, pattern);

MATLAB: How to recursively go through all directories and sub directories and process files

Since R2016b, dir can recurse through subdirectories using **. So it's as simple as:

rootdir = 'C:\somewhere\somedirectory';
filelist = dir(fullfile(rootdir, '**\*.*'));  %get list of files and folders in any subfolder
filelist = filelist(~[filelist.isdir]);  %remove folders from list
