Batch files and portions of file parameter

The following table outlines how you can modify the passed parameter.

Parameter Description
%1 The normal parameter.
%~f1 Expands %1 to a fully qualified pathname. If you passed only a filename from the current directory, this parameter would also expand to the drive or directory.
%~d1 Extracts the drive letter from %1.
%~p1 Extracts the path from %1.
%~n1 Extracts the filename from %1, without the extension.
%~x1 Extracts the file extension from %1.
%~s1 Changes the n and x options’ meanings to reference the short name. You would therefore use
%~sn1 for the short filename and %~sx1 for the short extension.

The following table shows how you can combine some of the parameters.

Parameter Description
%~dp1 Expands %1 to a drive letter and path only.
%~sp1 For short path.
%~nx1 Expands %1 to a filename and extension only.
