How do I save filenames in a for loop for later access?

I'm able to iterate through a given folder and display the names of all files. However, I want to save the names so did I can do work on each file. For example,
function fn = filnamn(katalog)
% displays the names of all files in given diretory
% Called with name of desired directory
fn = dir(katalog);
for k = 1:numel(fn)
if ~fn(k).isdir
disp(fn(k).name);
end
end
After each iteration how would I "append" each file so did I can access them afterwards?

C = cell(nnz(~fn(k).isdir), 1); % before loop
function C = filnamn(katalog)
% displays the names of all files in given diretory
% Called with name of desired directory
fn = dir(katalog);
for k = 1:numel(fn)
if ~fn(k).isdir
C{k} = fn(k).name;
end
end
