List only top directories

Dear Matlab_User

May I know the best approach to list down only the first level directories.

For example, I have a dir with subfolder inside, such as

C:\Users\1st_level_a\2nd_level
C:\Users\1st_level_b\2nd_level
C:\Users\1st_level_c\2nd_level\3rd_level.

However, I am only interested to obtain the url name for the 1st_level,

C:\Users\1st_level_a
C:\Users\1st_level_b
C:\Users\1st_level_c

I tried using the genpath (), however, genpath return me the sub dir as well.

Any suggestion is most welcome,

Cheers,

Rodney

I found a dirty workaround, but I welcome if there are any more efficient script to replace my method, thansk

 start_path = fullfile(matlabroot, 'C:\Users\');
  % Ask user to confirm or change.
  topLevelFolder = uigetdir(start_path);

list=dir(topLevelFolder);  %get info of files/folders in current directory
dirnames={list([list.isdir]).name};
dirnames=dirnames(~(strcmp('.',dirnames)|strcmp('..',dirnames)));

for i = 1:length (dirnames)
s (i) = strcat (topLevelFolder,'\', dirnames (i))
end

Try this:

startingFolder = 'C:/windows/media';
files = dir(startingFolder)
folderIndexes = [files.isdir]
folders = {files(folderIndexes).name} % Note, first two are . and ..
folders = folders(3:end) % Ignore . and .., if you want.
