Error using rmdir for deleting slprj folder

I would like to know why this rmdir comand does not work properly, this is the script made for deleting some variables and also the folder.

% % % %

current_path = pwd;

% %

%;

for k=1:64

FolderName=['CMkb1_',num2str(k)];

ruta=cd([current_path,'\',FolderName]);

delete Ib.mat

delete Ic.mat

delete IL.mat

delete Is.mat

delete kb1.mat

rmdir(ruta, "slprj\")

end

Error using rmdir

'slprj\' is an invalid option.

Error in Eliminar_mat_enSerie (line 17)

rmdir(ruta, "slprj\")

You cannot delete a folder if somebody is using it or looking at it, for example if you cd'd to that folder in MATLAB, have it open in File Explorer, have some document living there open in some program such as Excel, etc.

Don't use cd in your code. See the FAQ: https://matlab.fandom.com/wiki/FAQ#Where_did_my_file_go?_The_risks_of_using_the_cd_function.

Try this more robust, but untested, code:

currentFolder = pwd;
% Find out how many subfolders there are in the folder.
filePattern = fullfile(currentFolder, 'CMkb1*');
fileList = dir(filePattern);
numFolders = numel(fileList)
if numFolders == 0
    warningMessage = sprintf('No CMkb1* subfolders found under "%s"', currentFolder);
    uiwait(warndlg(warningMessage));
else
	% Delete files in subfolders, then the subfolder itself.
	for k = 1 : numFolders
		thisBaseFolderName = ['CMkb1_', num2str(k)];
		thisFullFolderName = fullfile(currentFolder, thisBaseFolderName);
		if ~isfolder(thisFullFolderName)
			% Skip this one if the folder does not exist.
			fprintf('Folder "%s" not found.\n', thisFullFolderName);
			continue;
		end
		% Delete the 5 .mat files.
		fileToDelete = fullfile(thisBaseFolderName, 'ib.mat');
		if isfile(fileToDelete)
			delete(fileToDelete)
		end
		fileToDelete = fullfile(thisBaseFolderName, 'Ic.mat');
		if isfile(fileToDelete)
			delete(fileToDelete)
		end
		fileToDelete = fullfile(thisBaseFolderName, 'IL.mat');
		if isfile(fileToDelete)
			delete(fileToDelete)
		end
		fileToDelete = fullfile(thisBaseFolderName, 'Is.mat');
		if isfile(fileToDelete)
			delete(fileToDelete)
		end
		fileToDelete = fullfile(thisBaseFolderName, 'kb1.mat');
		if isfile(fileToDelete)
			delete(fileToDelete)
		end
		% You could also use a loop to delete all .mat files, or just use a wildcard to delete them all in one shot.

		% Now remove the folder itself.  I think the folder must be totally empty.
		try
			rmdir(thisFullFolderName)
			fprintf('Folder "%s" removed.\n', thisFullFolderName);
		catch ME
			% Keep going even if this didn't work for this one folder.
		end
	end
end
