Hi,

I understand that you want to traverse folder which has subfolders, having csv files. You want to read csv files as a structure.

You can use dir to get the files and read files as tables and then convert the tables as structure.

The following code implements the above functionality.

%folder = path to the folder;
D=dir(fold)
%traverse from 3 to numel 
for i=3:numel(D)
    %subfolder
    currD=D(i).folder;
    %change directory
    cd(currD);
    fList=dir(D(i).name);
    f=fList.folder;
    for j=3:numel(fList)
        pa=fullfile(fList(j).folder,fList(j).name);
        %read filke as a table
        content=readtable(pa);
        %convert a table to a structure
        content=table2struct(content)
    end
    %go back to the previous folder
    cd(D(i).folder);
end
