How can I save values to an array using a for loop

I am trying to create an array or variable that stores filenames for later access. I have tried doing this with a for loop but am forgetting something or doing it wrong. My goal is something similar to:

folderName = [dir([read_dr '\some_folder'])]; %This works
for g = 1:length(folderName)
    fileNames = folderName(g).name;
end

disp(fileNames) % Will only show the last value

This will store the value but will only save the last one.

I have also tried:

folderName = [dir([read_dr '\some_folder'])]; %This works
fileNames = {};
for g = 1:length(folderName)
    fileNames(g) = folderName(g).name;
end

Which will give the error:

Conversion to cell from char is not possible.

Any help is greatly appreciated!

I'd try this

folderName = [dir([read_dr '\some_folder'])]; %This works
fileNames = {};
for g = 1:length(folderName)
    fileNames{g} = folderName(g).name;
end
