How to loop through N different folders with M different.txt files(text001.txt.....text010.txt) with (O rows and P columns). and plot the average(text001.txt.....text010.txt)of M different figures from the N folders.

D = 'D:\dataprocessing\';
S = dir(fullfile(D,'*'));
N = setdiff({S([S.isdir]).name},{'.','..'}); % list of subfolders of D.
sums = [];
counts = [];
for ii = 1:numel(N)
T = dir(fullfile(D,N{ii},'*')); % improve by specifying the file extension.
C = {T(~[T.isdir]).name}; % files in subfolder.
for jj = 1:numel(C)
F = fullfile(D,N{ii},C{jj})
fprintf('test%s\n',F);
S(ii).data = F(:);
end
end
X = vertcat(S.data);
avgArrivalDelay = sum(sums)/sum(counts)

Would the data fit in your memory all at once if you read all data and then did the processing?

Try this. Adapt as needed:
% Get a list of all txt files in the current folder, or subfolders of it.
fds = fileDatastore('*.txt', 'ReadFcn', @importdata)
fullFileNames = fds.Files
numFiles = length(fullFileNames)
% Loop over all files reading them in and plotting them.
for k = 1 : numFiles
fprintf('Now reading file %s\n', fullFileNames{k});
% Now have code to read in the data...
% Now code to plot the data...
end

Attach at least two of your data files so I can do it for you. Use the paper clip icon.
