Your variable "files" is a cell string, therefore you need curly braces. During the loop you overwrite the original "files" by a struct. The variable "myfile" is overwritten also - it looks really confused.

[filenames, pathname] = uigetfile('MultiSelect', 'on');
filenames = cellstr(filenames);  % EDITED

for n = 1:length(filenames)
  afile = fullfile(pathname, filenames{n});  % EDITED
  data = importdata(afile);
  % Remove the file extension file the name:
  [dummy, afilename] = fileparts(filenames{n});
  save(afilename, 'data');
end

If you want to save all data in one MAT file, explain this again with more details.

After some testing, it seems your file can be read by setting delimiter to 3x spaces.

You can combine this with the rest of your options here as needed.

opts = detectImportOptions('test.txt','Delimiter','   ','ConsecutiveDelimitersRule','join','ExpectedNumVariables',3,'LeadingDelimitersRule','ignore');
opts = setvartype(opts,'VALUEDIMENSIONS','char');
a = readtable('test.txt',opts);
