From the code below,I got the file names of multiple images from a folder.
clear all
close all
clc
Directory = 'Images_folder\';
Imgs = [dir(fullfile(Directory,'*.bmp')); dir(fullfile(Directory,'*.jpg'));
dir(fullfile(Directory,'*.png'));dir(fullfile(Directory,'*.tif'))];
% D = dir('images');
ID = 1;MDMF=2;IDMF=3;HD=4;UHD=5;
m=[ID,MDMF,IDMF,HD,UHD];%comma separation is necessary for errorles result
for j=1:length(Imgs)
Img = imread(fullfile(Directory,Imgs(j).name)); % Read image
% figure
% imshow(Img)
end
headers={'File_Name',};
for i=1:length(Imgs)
f_name =Imgs(i).name;
f_name = f_name(1:end-4);
filename = sprintf('%s',f_name);
disp(filename)
csvwrite('Myfile.csv',filename)
end

You cannot use csvwrite() or dlmwrite() to selectively overwrite columns. You would need to use xlswrite() or writetable() to selectively overwrite columns.
If you are just trying to create a new file with those entries as the only content, then the easiest way is to do it "manually". No loop is required:
fid = fopen('Myfile.csv', 'wt');
[~, f_names] = cellfun(@fileparts, {Imgs.name}, 'uniform', 0);
fprintf(fid, '%s\n', f_names{:});
fclose(fid);
