create subfolders that are the same as those in another folder

I have 2 folders, "GLOBAL" and "GLOBAL2" on the Desktop.

Inside the folder "GLOBAL" I have folders "DATA 1", "DATA 4", "DATA 5", etc.

I would like to create, using a for loop, folders inside "GLOBAL2" that have the same name as the folders inside "GLOBAL" (i.e. create inside "GLOBAL2" the folders "DATA 1", "DATA 4", "DATA 5", etc.).

I haven't found any clues on the Internet or maybe I'm looking wrong....

% get the folder contents
d = dir('C:\Users\Alberto\Desktop\GLOBAL');
for k = ????
    % remove all files (isdir property is 0)
    dfolders = d([d(:).isdir]);
    % remove '.' and '..' 
    dfolders = dfolders(~ismember({dfolders(:).name},{'.','..'}));
    dfolders_1 = dfolders.name;
    % subfolder creation
    subfolder = fullfile(d, sprintf(dfolders_1));
    if ~exist(subfolder, 'dir')
        mkdir(subfolder);
end

EDIT:

I am reading .jpg images within different folders:

Now reading C:\Users\Alberto\Desktop\GLOBAL\DATA 4\example\image_1.jpg
Now reading C:\Users\Alberto\Desktop\GLOBAL\DATA 4\example\image_2.jpg
Now reading C:\Users\Alberto\Desktop\GLOBAL\DATA 4\example\image_3.jpg
...
Now reading C:\Users\Alberto\Desktop\GLOBAL\DATA 6\example\image_1.jpg
Now reading C:\Users\Alberto\Desktop\GLOBAL\DATA 6\example\image_2.jpg
Now reading C:\Users\Alberto\Desktop\GLOBAL\DATA 6\example\image_3.jpg
...

I want to create the folders "DATA 4" and "DATA6" automatically inside another folder called "GLOBAL2":

folder_new = 'C:\Users\Alberto\Desktop\GLOBAL2';

Let me give a clearer example:

Now reading:

Now reading C:\Users\Alberto\Desktop\GLOBAL\DATA 4\example\image_1.jpg

I want to create a folder with the name "DATA 4" inside "GLOBAL2":

subF = 'C:\Users\Alberto\Desktop\GLOBAL2\DATA 4';

As soon as it is read:

Now reading C:\Users\Alberto\Desktop\GLOBAL\DATA 6\example\image_1.jpg

I want to create a folder with the name "DATA 6" inside "GLOBAL2":

subF = 'C:\Users\Alberto\Desktop\GLOBAL2\DATA 6';

I hope this is clear :)

I have spent some time to create a running version under your former question. I could not submit it, because you have deleted the question. Now this new question appears. Should I start to write an answer again?

[Alberto Acri]

Yes, thank you.

oldPath = 'C:\Users\Alberto\Desktop\GLOBAL';
newPath = 'C:\Users\Alberto\Desktop\GLOBAL2';

d        = dir(oldPath);
dfolders = d([d(:).isdir]);
dfolders = dfolders(~ismember({dfolders(:).name}, {'.','..'}));
for k = 1:numel(dfolders)
    mkdir(fullfile(newPath, dfolders(k).name));  % [EDITED] Typo fixed
end

I thank you for your reply, but it reports me this error:

Brace indexing is not supported for variables of this type.

in questa riga:

mkdir(fullfile(newPath, dfolders{k}));

[Jan]

@Alberto Acri: I've confused dfolders{k} with dfolders(k).name . Of course you can use the debugger to fix such problems by your own.

[Alberto Acri]

thank you, but it still doesn't work :)

[Jan]

@Alberto Acri: It would be useful to solve your problemn, if you mention, what "doesn't work" means. I cannot guess this detail.

[Alberto Acri]

Thank you. It works. Can you tell me how to extract a column present in the struct?

[Jan]

Which column of which struct do you want to extract? "Structs" do not have "columns".
