unable to make directory in specified folder

I have an issue using mkdir to create a folder to save my data.

datadir=fullfile('D:','Users','10513345');

cleandir=[datadir filesep 'data_refmast_512samplerate_71chan'];
if exist(cleandir,'dir')~=7
    mkdir(cleandir); 
end

The error I receive is: Error using mkdir

The system cannot find the file specified.

I have also tried just manually adding the folder and continue my code however later on it won't recognize this slef-made folder as a file or directory to put save the data.

So, im not really sure where in the progress matlab doesn't recognize the directory.

Hi mitchell

Have you tried this on a different location such as different folder in D: other than 'Users' or a completely different drive other than D:?

"it won't recognize this slef-made folder" Did you add it to Matlab's search path?

On my system, R2018b,Win10, your script works as expected. (There was no directory named Users on D: in advance.)

%%
datadir  = fullfile( 'D:', 'Users', '10513345' );
cleandir = fullfile( datadir, 'data_refmast_512samplerate_71chan' ); % stick to fullfile
if exist(cleandir,'dir')~=7
    mkdir(cleandir); 
end

Running the script a second time also worked as expected. i.e. did nothing.

Repacing D: by Z: (Z: doesn't exist) and running the script throws the error

Error using mkdir
The system cannot find the path specified.
Error in Untitled2 (line 5)
    mkdir(cleandir);     

Did mkdir really throw the error

    The system cannot find the file specified.    

There is no file involved.
