You should consider looking the the following files on MC:

DSK:CPM;.FILE. (DIR)
lists all the files on the CPM directory.  Files whose names are of the form
ARnn XXXX are really archives, or "subdirectories".  XXXX is chosen to be
descriptive of the contents of the archive.  Files whose names are of the form
TS XXXX are ITS executable files and are of no good to you.  All other files
are potentially interesting for FTP'ing.

ARnn:CPM;.FILE. (DIR)
lists all files in the ARnn archive on the CPM directory.

The advantage of the .FILE. (DIR) files over any CPM DIRLST files is that the
former are ALWAYS correct and fully up to date, as they are maintained by the
operating system.  (These files don't show up in directory listings because
they don't really exist.  They are just a way of asking ITS to make a directory
listing on the spot.)
