Create multiple copies of one file in multiple directories with different names

I want to create multiple folders. Let's say, the names of folders are- Folder 1, Folder 2, Folder 3 and so on.

In each folder, I would like to copy file "A.txt" and rename the file to "A_1.txt", "A_2.txt", "A_3.txt" and so on. How can I do that?

Try this.

Note: the file A.txt must be in the current folder

% data
N = 10;
dirName = 'Folder';
fileName = 'A';

% loop
for i = 1:N
    % create directory
    mkdir(strcat(dirName,num2str(i)));

    % copy file
    copyfile('A.txt',strcat(dirName,num2str(i),'/',fileName,'_',num2str(i),'.txt'));
end
