adding apostrophe for reading a folder name

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

Please show us the output of this command:

dir 'E:\Data_Sets\Fault\Outer\*clock

Hi Raady, is it supposed to be D: or is it supposed to be E: ?

[Raady]

 E:\Data_Sets\Fault\Outer\6 'o' clock\ is original path

@Stephen

The command is not working like the u gave me instead I have changed to the current folder and type dir

output is . .. 190.mat 191.mat 192.mat and so on .

I able to run the code if I rename the folder from "6 'o' clock" to 6_o_clock. it means it has some problem in string formatting. By seeing some examples i understood that when the name comes with ' symbol , it should be '' ( 2 times ) to make the matlab read as ' instead of reading it as start and end of string. So I have mentioned as '6 ''o'' clock'. but the problem is as mentioned above.

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
