The atime of a folder is changed when the file is read or executed (we only CD into a directory and then CD: will not cause atime changes, but ls will change atime).

< Span lang= "en-us" xml:lang= "en-US" >mtime   is a file in the folder to create new, delete will change (if you just change the contents of the file will not cause mtime changes)

the CTime of the folder is basically the same as the file ctime
