How to rename the subfolders

Hey Guys, I have 60 subfolders in a folder. Subfolder names are as follows: A_001, B_001,...Z_001, A_A_001, A_B_001, ....A_Z_001, A_A_A_001, A_A_B_001,.......

I want to rename the sub-folders as follows:

                                                          A_001=001,

                                                          B_001=002,

                              ...............             Z_001=026, 

                                                         A_A_001=027, 
                                                         A_B_001=028,

                                                         A_Z_001=052
............................................             A_A_A_001=053
Thanks in advance.

Please ensure that you make a backup before using this, and check that it is doing exactly what you want. I have not tested it, and you might need to make modifications.

Assuming that the top folder's name is stored as a string in the variable 'top_folder':

d = dir(top_folder);
fnames = {d.name};
% remove pseudo-folders . and ..
dotstart = cellfun(@(s) strcmp(s(1), '.'), fnames);
fnames(dotstart) = [];

maxlen = max(cellfun(@length, fnames));
% pad filenames on front with 'A'
fnames_padded = cellfun(@(s) char(padarray(double(s), [0 maxlen-length(s)], ...
    double('A'), 'pre')), fnames, 'UniformOutput', false);
[~, sort_index] = sort(fnames_padded);
fnames_sorted = fnames(sort_index);

for f = 1:length(sort_index)
   fname = fnames_sorted{i};
   fout = sprintf('%03d', f);
   fprintf('Moving %s\n      to %s\n', fname, fout);
   movefile(fullfile(top_folder, fname), fullfile(top_folder, fout));
end
