Using movefile can help you. Below is an example script. Please create an empty folder and set the folder as a current folder of MATLAB.

You can run the script below to learn how finding folder names and changing them works.

basepath = pwd;
%% Creating environment
for i_main = 1:100
    % creating 100 main folders
    mkdir("main" + i_main) 
    cd(fullfile(basepath, "main"+i_main))
    % creating a subfolder named "subfolder1"
    mkdir("subfolder1")
    % creating 20 files inside subfolder1
    cd(fullfile(basepath, "main"+i_main,"subfolder1"))
    for i_file = 1:20
        fid = fopen("file"+i_file+".txt", "w");
        fprintf(fid, "foo");
        fclose(fid);
    end
    cd(basepath)
end

%% find a subfolder and change its name
cd(basepath)
D = dir;
% removing current path or previous path
idx2del = strcmp(string({D.name}), ".") | strcmp(string({D.name}), "..");
D(idx2del) = []; 

names_mainfolder = {D.name};
for i_main = 1:length(names_mainfolder)
    cd(fullfile(basepath, names_mainfolder{i_main}))

    % finding the name of subfolder
    D = dir;
    idx2del = strcmp(string({D.name}), ".") | strcmp(string({D.name}), "..");
    D(idx2del) = []; 

    % changing the name of subfolder into the main folder
    movefile(D.name, names_mainfolder{i_main})
end
