I am using "dir" function to read folder names from a particular directory. Sometimes the function returns some empty or hidden folder names such as "." or "..". How can I get rid of these empty folder names?

This workflow can be achieved by filtering and removing the folder names which match to that pattern such as such as '.' '..' by using indexing.
For example,
files = dir;
folderNames = {files([files.isdir]).name};
folderNames = folderNames(~ismember(folderNames ,{'.','..'}));
