YourFolder='C:\Documents and Settings\Mes documents\MATLAB'
f=dir(fullfile(YourFolder,'*.txt'));
g={f.name};
s=regexp(g,'\d+','match');
s= str2double([s{:}]);
[n,idx]=sort(s);
g=g(idx);
for k=numel(g):-1:1
  fic=g{k};
  fic1=regexprep(fic,num2str(n(k)),num2str(n(k)+1));
  movefile(fullfile(YourFolder,fic),fullfile(YourFolder,fic1))
end
