Is there any other option to save these images in a folder?

No, there is no other way to save the images in a folder. No matter which folder you make your current folder, and no matter whether you use a relative path or a complete path, you still end up using imwrite() or equivalent, and you still risk being denied write access.

You need to figure out why it is not permitting you to save in that location.

I have to wonder why you have matlab\myfiles\matlab\myfiles in your path instead of just matlab\myfiles

create_missing = false;
parts = {'C:\', 'Users', 'Dell', 'Desktop', 'python tutorials', 'matlab', 'myfiles', 'matlab', 'myfiles', 'Dataset 2', 'Enhanced images'};
if ~exist(parts{1}, 'dir')
    error('You do not have a C: drive. Giving up.');
end
failed = false;
for K = 2 : length(parts)
    thispath = fullfile(parts{1:K});
    if exist(thispath, 'dir')
        fprintf('Okay we already have directory %s\n', thispath);
    elseif create_missing
        try
            mkdir(thispath);
            fprintf('Was able to create missing directory %s\n', thispath);
        catch
            fprintf('Failed trying to create missing directory %s', thispath);
            oldpath = fullfile(parts{1:K-1});
            p = fileattrib(oldpath);
            fprintf('Attributes of parent directory %s are:\n', oldpath);
            disp(p);
            failed = true;
            break
        end
    else
      fprintf('Directory %s does not exist and you asked that missing directories not be created. Set the variable create_missing to true if you want the directory created\n', thispath);
      failed = true;
      break
    end
end
if failed
    fprintf('Some directory not created. Not ready to use\n');
else
    fprintf('Okay, should be ready to use directory %s\n', fullfile(parts{:}) );
end
