26) COPY. A:

    The use of a decimal point IMMEDIATELY after some DOS statements,
    will replace *.*

    EXAMPLES: DEL.       (erase all files in current directory)
              COPY. A:   (copy all files in current directory to A:)

    There may be more statements with which it works, but I haven't
    tried them yet.

    "." means the current directory, and Command.com will assume that
    \directory implies \directory\*.* for most commands where a
    filename(s) should be specified, eg:

    DIR \ is the same as DIR \*.*
    COPY \FRED is the same as COPY \FRED\*.*
    COPY. A:\ is the same as COPY .\*.* A:\ which is the same as COPY *.* A:\
    DEL. is the same as DEL .\*.* which is the same as DEL *.*

    Have you noticed also how DIR ... only displays directories, not files?

                              Gary Marden

    In DOS 5.0 it displays directories and files with no extensions.
    I tried "DIR ...", "DIR...", and "DIR ....".  They all behave
    the same way.

    Another good thing is you can travel from directories to
    directories without typing "CD".  Just type the directory name
    followed by a backslash '\'.

    Example: To go from C:\BATCH to C:\WP51, you type "\wp51\".
    That's it!  fast and easy.

    If you are in the following directory :

        \WORD\FILES\LETTERS\APRIL

    And wanted to go to the directory \WORD\FILES, you'd normally 
    type two lines : 

         CD \
         CD WORD\FILES

    Or even the single line "CD \WORD\FILES" to combine the two 
    commands into one. There is a shorter way, simply type the 
    following : CD ..\..     You're there !

                              Andrew Barnhardt
           
    In DOS 5.0, it displays files and directories which have no extension.

                              Larry Kessler

    On this machine with DOS 5.0 and NDOS 6.0 DIR... gives me a list of
    subdirectories off of the root and a list of all files in the root
    directory, regardless of the file extension.  It will yield this result
    regardless of what directory/subdirectory I am in at the time the command
    is issued.

    Editor's Note:

    I admit that "features" in the last two MUFs may be documented
    (although obscure feature), the reason that it continues to be
    seen in the MUF list is because I believe that the ability to use
    the period immediately IE: COPY. is not documented.  What is
    documented is the fact that "." and ".." can be used to represent
    the current and parent directories respectively, and these will work
    with many applications which can handle directory names as arguments.
    In this case the "." could also be viewed as a replacement for "*.*"
