I want the following code to loop through multiple folders instead of having to open each folder individually so that I can do batch file processing.

directory = uigetdir('*',"Select Folder With Files To Be Processed");
You could change that to
parentdirectory = uigetdir('*', 'Select Folder with folders inside it');
if isnumeric(parentdirectory); return; end %user cancel
dinfo = dir(parentdirectory);
dinfo(~[dinfo.isdir]) = []; %remove ordinary files
dinfo(ismember({dinfo.name}, {'.', '..'})) = []; %remove . and ..
for K = 1 : length(dinfo)
directory = fullfile(dinfo(K).folder, dinfo(K).name);
%now all of the normal steps
end

Is the figure call inside the for K loop ? If so then are you getting one figure for every folder, or are you getting only one figure total? If you are getting one figure for every folder, then is the plot content the same for all of them?
I wonder if you did not fill in the place where I wrote
%now all of the normal steps
Inside that for K loop you should have all of the lines from
% List all items in the folder
through to the hold off
all inside the for K loop.

Oh I am dumb and didn't see the other "end" when I copied over the code! Thanks so much it worked great!
