Did you try

files = {'example- IND.X0kY0k.HXX.txt', 'example- IND.X0kY0k.HXY.txt'};
target = replace(files, '.HXX.txt', '.txt');
% Be careful with others because they'd overwrite the .HXX one.
%target = replace(files, '.HXY.txt', '.txt');
%target = replace(files, '.HXZ.txt', '.txt');
cellfun(@(x, y)movefile(x, y), files, target)
