open a list fo file with fopen???

It gives problem for the fileID.

File_info = dir('*.lis'); 
filename = {File_info.name};
[m,nfile]= size(filename);
for ifile= 1:nfile
  delimiter = {' ',';'};
  formatSpec = '%s%s%s%s%s%s%[^\n\r]';
  fileID=fopen(filename{ifile}, 'r');
  dataArray = textscan(fileID, formatSpec, 'Delimiter', delimiter, 'MultipleDelimsAsOne', true,  'ReturnOnError', false);
  fclose(fileID);
end

I fixed your formatting, but please read this link for next time.

Also please read this link and post your error message - you forgot to. Be sure to include ALL the red text, not just part of it.

Well it was a step along the way. I'm sure there was something in there about attaching your data so people can reproduce your situation. I guess you didn't read it because you didn't attach the file. You didn't even attach all the red text of your error message like I asked directly in the comment. Did you even look at all I could do (given what you've provided) in my answer below? Come on, make it easy for us to help you not hard.

Here's some improved code:

delimiter = {' ',';'};
formatSpec = '%s%s%s%s%s%s%[^\n\r]';
File_info = dir('*.lis');
allFileNames = {File_info.name};
[m,nfile]= size(allFileNames)
numFilesProcessed = 0;
for ifile= 1:nfile
  thisFileName = fullfile(pwd, allFileNames{ifile});
  fprintf('Processing %s\n', thisFileName);
  fileID=fopen(allFileNames{ifile}, 'r');
  if fileID ~= -1
    % File is good.
     dataArray = textscan(fileID, formatSpec, 'Delimiter', delimiter, 'MultipleDelimsAsOne', true,  'ReturnOnError', false);
    fclose(fileID);
    numFilesProcessed = numFilesProcessed + 1;
  else
    message = sprintf('Cannot open this file:\n%s', thisFileName);
    uiwait(warndlg(message));
  end
end
fprintf('Done!\nProcessed %d files.\n', numFilesProcessed);
