Substitution of batch parameters (%n) has been enhanced.  You can
Now use the following optional Syntax:

    %~1         - expands %1 removing any surrounding quotes (")
    %~f1        - expands %1 to a fully qualified path name
    %~d1        - expands %1 to a drive letter only
    %~p1        - expands %1 to a path only
    %~n1        - expands %1 to a file name only
    %~x1        - expands %1 to a file extension only
    %~s1        - expanded path contains short names only
    %~a1        - expands %1 to file attributes
    %~t1        - expands %1 to date/time of file
    %~z1        - expands %1 to size of file
    %~$PATH:1   - searches the directories listed in the PATH
                   environment variable and expands %1 to the fully
                   qualified name of the first one found.  If the
                   environment variable name is not defined or the
                   file is not found by the search,then this
                   modifier expands to the empty string

The modifiers can be combined to get compound results:

    %~dp1       - expands %1 to a drive letter and path only
    %~nx1       - expands %1 to a file name and extension only
    %~dp$PATH:1 - searches the directories listed in the PATH
                   environment variable for %1 and expands to the
                   drive letter and path of the first one found.
    %~ftza1     - expands %1 to a DIR like output line

In the above examples %1 and PATH can be replaced by other
valid values.  The %~ Syntax is terminated by a valid argument
number.  The %~ modifiers may not be used with %*
