Saving summed matrixes seperately after a for loop

Hi all:
I have this code that is working but just needs a little help. I am doing summing of 12 variables in a (struct frame of 12 files) repeatedly until the end. I want the results to be saved with increment filenames or unique identifiers, but it keeps on overwriting the previous operations. Thanks in advance and credit to Jason who helps edited the initial code:
dirname = uigetdir;
Files = dir(fullfile(dirname,'*.mat'));
N = length(Files);
count = 0;
for i = 1:N
if count == 0
Total = zeros(1800,3600);
end
count = count + 1;
FileData = load(fullfile(dirname, Files(i).name));
Total = Total + FileData.gpm.Frame;
count = count + 1;
if count == 12
filename = sprintf('%s_%d','Total',count); % what I want to do here is to be saving the files separately with unique identifier after each operation, but instead it keeps on over-writing.
save(filename);
count = 0;
end
end

It's not overwriting. The if statement
if count == 12
ensures that your operation of interest will only ever be done in the single case when count==12. Perhaps you should remove it from the if...end block.
