What Are Batch Parameter Modifiers?

Batch parameter modifiers are special functions that you can apply to batch parameters to modify their values.

Here is a list batch parameter modifiers presented in formats for the 1 parameter. But you can use them on any of %0, %1, %2, ..., %9.

%~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

You can also apply multiple modifiers together as shown below. The order of modifier locations is not important.

%~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
