How to name files in a folder based on parent folder?

Hello all,

I'm newbie to Matlab and I got a question regarding naming files in folders. I have 6 folders let's say simulation_data1 to 6, and there are 17 pictures in each folders which are named block_1 to 17 now in all 6 folders. I was wondering how can I name each batch of pictures (17 figs) in every folder based on the name of parent folder? For example, all figs in folder simulation_data1 become simulation_data1_1 to 17.

any help would be appreciated.

regards

for i=1:6   % 6 folders
    foldername = sprintf('simulation_data%d', i)
    mkdir(foldername)
    cd(foldername)
    
    for j=1:2       % 2 files for example
        filename = sprintf('%s_%d', foldername, j);
        fprintf('   Filename: %s\n', filename)
        save(filename, 'filename');         % create a file
    end
    cd( '..');
end

foldername = 'simulation_data1'

   Filename: simulation_data1_1
   Filename: simulation_data1_2

foldername = 'simulation_data2'

   Filename: simulation_data2_1
   Filename: simulation_data2_2

foldername = 'simulation_data3'

   Filename: simulation_data3_1
   Filename: simulation_data3_2

foldername = 'simulation_data4'

   Filename: simulation_data4_1
   Filename: simulation_data4_2

foldername = 'simulation_data5'

   Filename: simulation_data5_1
   Filename: simulation_data5_2

foldername = 'simulation_data6'

   Filename: simulation_data6_1
   Filename: simulation_data6_2

dir

.                 ..                simulation_data1  simulation_data2  simulation_data3  simulation_data4  simulation_data5  simulation_data6

Thanks for your reply, even though the code creates new mat files and did not renamed the present pictures. So if there is a way to rename the existing png pictures in the folders?

[Chunru]

You can ajust the code for your need:

for i=1:6   % 6 folders
    foldername = sprintf('simulation_data%d', i)
    mkdir(foldername)
    cd(foldername)
    
    for j=1:2       % 2 files for example
        filename_old = sprintf('block%d.png', j);
        filename_new = sprintf('%s_%d.png', foldername, j);
        movefile(filename_old, filename_new);
    end
    cd( '..');
end

Thanks a billion for your attention, however mkdir(foldername) overwrites the present folders and data, so it remains pointless.

[Chunru]

Just remove it. It is used to generate data (as I don't have your data).

Thanks a lot. I fixed it.
