How can I copy files from multiple subfolders into a new folder and rename them while doing so?

Hi, I'm having a few problems figuring this out and I hope someone can help me:

I have multiple folders with differnet names (i.e. 1_5, 1_10 etc.) and each of them contains a subfolder (Erg), which contains another subfolder named DV.

In this last subfolder there is a specific file which always has the same name (solution_1).

Now I want to copy all solution_1 files in a newly created soltution folder and add a prefix so that each file has the name of the "masterfolder" in front of it.

Like this: 1_5_solution_1, 1_10_solution_1 etc.

I tried to visualize the folder structure below:

- 1_5
    - Erg
        - DV
            - solution_1.txt
- 1_10
    - Erg
        - DV
            - solution_1.txt
- solutions
    - 1_5_solution_1.txt
    - 1_10_solution_1.txt

I hope it is understandable and someone can help me.

Have a great day and thank you in advance!

hi,

if your all folder's are same structure. pl use this code.

common_folder1 = 'Erg';
common_folder2 = 'DV';
outputFolder = 'solutions';
get_folder = dir;

for i1 = 3 : length(get_folder)
    if isdir(get_folder(i1).name)
        dir1 = [pwd, '\', get_folder(i1).name,'\', common_folder1, '\', common_folder2 ];
        d = dir(fullfile(dir1, '*.txt'));
        if ~isempty(d)
            if ~exist(outputFolder, 'dir')
                mkdir(outputFolder);
            end
            file_name = [get_folder(i1).name '_' d.name];
            copyfile([dir1 '\' d.name], [pwd '\' outputFolder, '\',file_name]);
        end
    end
end

Rather than using a hard-coded separator character like this:

dir1 = [pwd, '\', get_folder(i1).name,'\', common_folder1, '\', common_folder2 ];

it is strongly recommended to use simpler and more robust fullfile:

dir1 = fullfile(pwd, get_folder(i1).name, common_folder1, common_folder2);

Thank you very much! Both of you! This works perfectly :)
