Using the LS command and catching the CHAR array output is not stable, because it kills trailing spaces. Better:
list_files2load = dir('*.txt');
files = {list_files2load.name};
m = length(files);
for j=1:m
sprintf('loading file : %s', files{j})
s = load(files{j});
s(:,7)=s(:,7).*pi;
s(:,8)=s(:,8).*pi;
save(fullfile('D:\Temp\', files{j}), 's');
end
