Expansion of Input Parameters for Batch Command

Code

Consider that one of several input parameters, the first argument C:\data\ABC.csv, is passed as %1 with a tilde included. Various functionalities of this input argument are introduced¹.

Syntax	Origin	Description	Result
%~f1	Full path	Full path	C:\data\ABC.csv
%~d1	Drive	Drive	C:
%~p1	Path	Path	\data\
%~n1	Name	Name	ABC
%~x1	eXtension	Extension	.csv

Combination

The input argument can also be used in combination. Although combinations like %~dn1 may not have proper meaning as a file’s location, they can be cleverly used depending on the situation.

Combination	Result
%~dp1	C:\data\
%~nx1	ABC.csv
%~dn1	C:ABC
%~nd1	C:ABC

As can be seen in the examples of %~dn1 and %~nd1, the order does not matter.
