Compare directories
 This  command  compares  the  contents  of  the  directories
 displayed in two panels. Files  found in one  directory  but
 not the other are marked. Files that  have  been  created or
 edited  more recently in one than the other are also marked.
 If the two directories are identical, the Commander displays
 a message to that effect.

 To  make   two   directories  identical,  use   the  Compare
 directories  command, then  press F5, Enter in each panel to
 copy the newer or unique files to the other directory.

    Marks:

      1. Files  that have a more recent date than file in the
         other panel.

      2. Files that don't exist in the other panel.
