How do I import multiple .dat files from a folder in Matlab?

I have multiple folders such as Instance01, Instance02, Instance03, etc and each folder contains many ".dat" files which are named as time.dat, cost.dat, pred.dat, etc. In my problem, i first works on the .dat files in folder Instance01, once execution is done, Instance02 needs to be accessed and so on. Now my question is that "How can I access all the .dat files in each folder sequentially?"

datFiles = dir("*.dat"); 
N = length(datFiles) ; 
% loop for each file 
for i = 1:N
    thisFile = datFiles(i).name ; 
    % do what you want 
end
