Create folders in matlab and move into files via loop

Hello,

I am making via a loop 4 .txt files. I would like to create 4 files and move each one of 4.txt files in these 4 folders (I mean each folder would have one .txt files).

How could I make it?

You may try the following

for i =1:4
currentFolder = sprintf('Folder%d',i);
mkdir(currentFolder)
cd(currentFolder)
fileID = fopen('FileName.txt','w');
% Write to file 
cd ..
end

Ok, thank you , but the point is that my loop creates the files I want, I would like before making the next file to put it into the folder. I mean that the files are not empty.

Do you know what I have to do?

[Sai Sri Pathuri]

You may still use this code. Add the code related to creation of files at the place of Create the file comment.

for i =1:4
currentFolder = sprintf('Folder%d',i);
mkdir(currentFolder)
cd(currentFolder)
% Create the file
cd ..
end 

If this doesn't help, Can you share your loop?

[Ivan Mich]

the loop is :

for n=1:numel(st);
for i=1:size(nam);
    FP=fopen(sprintf('m%g0.txt',i),'wt');
    fprintf(FP,'%s\t',num2str(Results));  
    fclose(FP);
    
    D = 'absolute/relative path to where the files are saved';
    N = 25; % number of files
    C = cell(1,N);
    for k = 1:N
        F = fullfile(D,sprintf('m%u.txt',k));
        C{k} = dlmread(F);
    end
    M = vertcat(C{:});
    dlmwrite('final.txt',M,'\t')

end
end

To sum up I would like to create multiple folders, in each one to be contained 1 final .txt file, after each iteration (eg two folders two and each folder contains a final.txt file).

Try the following code

for n=1:numel(st);
for i=1:size(nam);
% Uncomment below line to create folder for each m*.text file     
    % currentFolder = sprintf('Folder%d%d',n,i);
    % mkdir(currentFolder)
    % cd(currentFolder)
    FP=fopen(sprintf('m%g0.txt',i),'wt');
    fprintf(FP,'%s\t',num2str(Results));  
    fclose(FP);
    % cd ..
    
    D = 'absolute/relative path to where the files are saved';
    N = 25; % number of files
    C = cell(1,N);
    for k = 1:N
        F = fullfile(D,sprintf('m%u.txt',k));
        C{k} = dlmread(F);
    end
    M = vertcat(C{:});
    % Create a folder for each final.txt
    currentFolder = sprintf('FinalFolder%d%d',n,i); 
    mkdir(currentFolder)
    cd(currentFolder)
    dlmwrite('final.txt',M,'\t')
    cd ..

end
end

ok, one question. Is there any way to replace dlmwritte with writematrix? I think that the problem is here

[Sai Sri Pathuri]

Yes, you may replace dlmwrite with writematrix

writematrix(M,'final.txt','Delimiter','tab')

Refer the below links for replacing dlmwrite and dlmread with writematrix and readmatrix respectively
