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
