Try this:
filesStructure = dir('./JAAD_frames/video_0001/*.*')
allFileNames = {filesStructure(:).name}
for k = 1 : length(allFileNames)
fprintf('allFileNames{%d} = %s\n', k, allFileNames{k});
end

for i=1:numel(im_filenames)
print(im_filenames.name, im_filenames.folder)
end

Very clean solution but I get this error
Error using inputcheck
Multiple inputs that look like file names: '.' and '..'.
Error in print (line 41)
[pj, devices, options ] = inputcheck( pj, inputargs{:} );
Error in untitled (line 6)
print(im_filenames.name, im_filenames.folder)

It's nothing to do with the loop. Use dir() to get only the folder contents that are file names.
