I guess one of the files didn't have '080' in the name (possibly because it was already renamed by a previous run of this code).

To handle that situation, I skip the file in that case:

your_directory = 'C:\path\to\some\folder';
s = dir(fullfile(your_directory,'*.txt'));
old_file_names = fullfile(your_directory,{s.name});
new_file_names = fullfile(your_directory,strrep({s.name},'080','020'));
for ii = 1:numel(old_file_names)
    if strcmp(old_file_names{ii},new_file_names{ii})
        continue
    end
    movefile(old_file_names{ii},new_file_names{ii});
end
