Hi,
I have files like B00001.im7 ..... B10000.im7 inside the particular folder, Here, I intend to replace 'B' by 'P'
for e.x. B00001.im7 to P00001.im7. Please suggest the way to do this..

movefile
movefile source destination
movefile 'B00001.im7' 'P00001.im7' % or supply full path to the files

This should do it.
Dir_files = dir('*.im7');
List_Files = {Dir_files.name}'; % Cell (length(Dir_files, 1) that contain filenames
List_Files(:,2) = List_Files(:,1); % Copying cells to second column
for ii = 1:length(List_Files)
List_Files{ii,2}(1) = 'P'; % Change first character in 2nd column of each file
movefile (List_Files{ii,1}, List_Files{ii,2});
end
