In fact, we have already done this job. For example:

% ~

You can remove the quotation marks on both sides of the parameter.

This is the parameter table about the parameters in this document.

 

Modifier	Description
% ~ 1	Expands % 1 and removes any surrounding quotation marks ("").
% ~ F1	Expands % 1 to a fully qualified path name.
% ~ D1	Expands % 1 to a drive letter.
% ~ P1	Expands % 1 to a path.
% ~ N1	Expands % 1 to a file name.
% ~ X1	Expands % 1 to a file extension.
% ~ S1	Expanded path contains short names only.
% ~ A1	Expands % 1 to file attributes.
