I am trying to files in that directory which have folder name as "6 'o' clock".

    filefolder = fullfile(dataset_folder,'6 ''o'' clock');
    load(fullfile(filefolder,'234.mat');

it gives me this error:

    Error using load 
    Unable to read file 'E:\Data_Sets\Fault\Outer\6 'o' clock\234.mat': no such file or directory.

I am able to read the folders which doesnt have the apostrophe, but not with the apostrophe. how to do it My path in windows is

E:\Data_Sets\Fault\Outer\6 'o' clock\

and i have files from 190.mat to 290.mat in this folder

Okay, what are the exact outputs of these commands:

dir E:\Data_Sets\Fault\Outer\
exist('E:\Data_Sets\Fault\Outer','dir')
exist('E:\Data_Sets\Fault\Outer\6 ''o'' clock','dir')

@Raady: Do you understand, what we are asking for? We assume, that your folder is not called "6 'o' clock", but that there are some unexpected characters in the name. Perhaps these are different quotes like ´ or `, or the spaces are not spaces, but invisible non-printable characters. Running my code would reveal this.

Check the name twice. Are there any unicode characters in the name?

FileList = dir('E:\Data_Sets\Fault\Outer\6*');
Name     = {FileList.name};
for iName = 1:numel(Name)
  fprintf('\n%s\n', Name{iName});
  fprintf('%d ', double(Name{iName}));
end

Try this:

quote = 39; % ASCII value for a single quote.
subFolder = sprintf('6 %co%c clock', quote, quote) % Create string: 6 'o' clock
fileFolder = fullfile(dataset_folder, subFolder) % Prepend another folder.
fullFileName = fullfile(fileFolder, '234.mat') % Construct the full file name of the mat file.
% Try to load the file.  Warn if it does not exist.
if exist(fullFileName, 'file')
  load(fullFileName);
else
  errorMessage = sprintf('Error: File not found:\n%s', fullFileName);
  uiwait(errordlg(errorMessage));
end
