Argument Expansion

Replace n with argument number (0, 1, etc). Most useful when working with %0, the Batch file itself.

• %~n - expands %n removing any surrounding quotes (“)
• %~fn - expands %n to a fully qualified path name
• %~dn - expands %n to a drive letter only
• %~pn - expands %n to a path only
• %~nn - expands %n to a file name only
• %~xn - expands %n to a file extension only
