Try this
% Specify the folder where the files live.
myFolder = pwd; %or 'C:\Users\yourUserName\Documents\My Pictures' or wherever.
% Check to make sure that folder actually exists. Warn user if it doesn't.
if ~isfolder(myFolder)
errorMessage = sprintf('Error: The following folder does not exist:\n%s\nPlease specify a new folder.', myFolder);
uiwait(warndlg(errorMessage));
myFolder = uigetdir(); % Ask for a new one.
if myFolder == 0
% User clicked Cancel
return;
end
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.txt'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
% Loop over all filenames.
for k = 1 : length(theFiles)
baseFileName = theFiles(k).name;
fullFileName = fullfile(theFiles(k).folder, baseFileName);
% Skip the bad file, which has a known filename.
if strcmpi(baseFileName, 'some really bad file.txt')
continue; % Skip to bottom of loop and keep iterating with remaining files.
end
fprintf(1, 'Now reading %s\n', fullFileName);
% Now do whatever you want with this file name,
% such as reading it in as an array with readmatrix()
% imageArray = readmatrix(fullFileName);
end
Adapt as needed.

@Ihaveaquest isn't this code " an examle of what you mean"??? If not, why not?
