SubFolder = dir(fullfile(app.datasetFolder,'*'));
folderSize = setdiff({SubFolder([SubFolder.isdir]).name},{'.','..'});
if(size(folderSize,2) == 0)
errordlg('Folder does not have any data');
else
disp(folderSize)
end

Use this Recursive Directory File Exchange contribution, and add up all the bytes fields.
Note: the meaning if bytes on a directory entry would depend upon your operating system.

This does the trick:
D = dir('**/*.mat'); % descends current folder and its sub-folders
total_bytes = 0;
for ii = 1:length(D)
total_bytes = total_bytes + D(ii).bytes;
end
